Input saturation leads to controller windup, removable by structural modification during compensator realization and plant windup which calls for additional dynamics. This book presents solutions to the windup prevention problem for stable and unstable single-input-single-output and multiple-input-multiple-output (MIMO) systems.
Download or read book Windup in Control Owing to Sensor Saturation written by Peter Hippe and published by Springer Nature. This book was released on 2021-05-17 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This brief presents methods for anti-windup control in the presence of saturating sensors, arbitrary external reference inputs, and constant or step-like disturbance inputs. It also offers techniques to assure windup prevention when both the input and the output signals are limited and this for systems with one input (SISO) and multiple inputs (MIMO). The emphasis in both is on real-world practicality rather than rigorously proven stability. Two novel solutions for anti-windup control are explored. The first approach, for SISO systems only, follows the classic design paradigm of anti-windup control: design an arbitrary linear compensator and add appropriate measures for their prevention if saturation causes stability problems. This uses a saturation indicator detecting the presence, but not the extent of saturation. The second methodology uses a compensator design that assures the desired rejection of persistent disturbances without jeopardizing closed-loop stability, and can be applied to SISO and MIMO systems alike. Containing worked examples that can be reproduced by the reader, illustrative simulations, and open problems for future research, Windup in Control Owing to Sensor Saturation will be of interest to both academics and engineers in the fields of control and process industries.

Download or read book Applied Control Theory for Embedded Systems written by Tim Wescott and published by Elsevier. This book was released on 2011-03-31 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many embedded engineers and programmers who need to implement basic process or motion control as part of a product design do not have formal training or experience in control system theory. Although some projects require advanced and very sophisticated control systems expertise, the majority of embedded control problems can be solved without resorting to heavy math and complicated control theory. However, existing texts on the subject are highly mathematical and theoretical and do not offer practical examples for embedded designers. This book is different;it presents mathematical background with sufficient rigor for an engineering text, but it concentrates on providing practical application examples that can be used to design working systems, without needing to fully understand the math and high-level theory operating behind the scenes. The author, an engineer with many years of experience in the application of control system theory to embedded designs, offers a concise presentation of the basics of control theory as it pertains to an embedded environment. - Practical, down-to-earth guide teaches engineers to apply practical control theorems without needing to employ rigorous math - Covers the latest concepts in control systems with embedded digital controllers

Book excerpt: NATIONAL BESTSELLER • A "fresh, genre-bending thriller” (Los Angeles Times) set in the near future when water is scarce and a spy, a hardened journalist and a young Texas migrant find themselves pawns in a corrupt game. "Think Chinatown meets Mad Max." NPR, All Things Considered In the near future, the Colorado River has dwindled to a trickle. Detective, assassin, and spy, Angel Velasquez “cuts” water for the Southern Nevada Water Authority, ensuring that its lush arcology developments can bloom in Las Vegas. When rumors of a game-changing water source surface in Phoenix, Angel is sent south, hunting for answers that seem to evaporate as the heat index soars and the landscape becomes more and more oppressive. There, he encounters Lucy Monroe, a hardened journalist with her own agenda, and Maria Villarosa, a young Texas migrant, who dreams of escaping north. As bodies begin to pile up, the three find themselves pawns in a game far bigger and more corrupt than they could have imagined, and when water is more valuable than gold, alliances shift like sand, and the only truth in the desert is that someone will have to bleed if anyone hopes to drink.

Download or read book Fractional order Systems and PID Controllers written by Kishore Bingi and published by Springer Nature. This book was released on 2019-10-31 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a detailed study on fractional-order, set-point, weighted PID control strategies and the development of curve-fitting-based approximation techniques for fractional-order parameters. Furthermore, in all the cases, it includes the Scilab-based commands and functions for easy implementation and better understanding, and to appeal to a wide range of readers working with the software. The presented Scilab-based toolbox is the first toolbox for fractional-order systems developed in open-source software. The toolboxes allow time and frequency domains as well as stability analysis of the fractional-order systems and controllers. The book also provides real-time examples of the control of process plants using the developed fractional-order based PID control strategies and the approximation techniques. The book is of interest to readers in the areas of fractional-order controllers, approximation techniques, process modeling, control, and optimization, both in industry and academia. In industry, the book is particularly valuable in the areas of research and development (R&D) as well as areas where PID controllers suffice – and it should be noted that around 80% of low-level controllers in industry are PID based. The book is also useful where conventional PIDs are constrained, such as in industries where long-term delay and non-linearity are present. Here it can be used for the design of controllers for real-time processes. The book is also a valuable teaching and learning resource for undergraduate and postgraduate students.

This book was released on 2011-08-13 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph details basic concepts and tools fundamental for the analysis and synthesis of linear systems subject to actuator saturation and developments in recent research. The authors use a state-space approach and focus on stability analysis and the synthesis of stabilizing control laws in both local and global contexts. Different methods of modeling the saturation and behavior of the nonlinear closed-loop system are given special attention. Various kinds of Lyapunov functions are considered to present different stability conditions. Results arising from uncertain systems and treating performance in the presence of saturation are given. The text proposes methods and algorithms, based on the use of linear programming and linear matrix inequalities, for computing estimates of the basin of attraction and for designing control systems accounting for the control bounds and the possibility of saturation. They can be easily implemented with mathematical software packages.

Download or read book PID Control written by Michael A Johnson and published by Springer Science & Business Media. This book was released on 2005-12-28 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effectiveness of proportional-integral-derivative (PID) controllers for a large class of process systems has ensured their continued and widespread use in industry. Similarly there has been a continued interest from academia in devising new ways of approaching the PID tuning problem. To the industrial engineer and many control academics this work has previously appeared fragmented; but a key determinant of this literature is the type of process model information used in the PID tuning methods. PID Control presents a set of coordinated contributions illustrating methods, old and new, that cover the range of process model assumptions systematically. After a review of PID technology, these contributions begin with model-free methods, progress through non-parametric model methods (relay experiment and phase-locked-loop procedures), visit fuzzy-logic- and genetic-algorithm-based methods; introduce a novel subspace identification method before closing with an interesting set of parametric model techniques including a chapter on predictive PID controllers. Highlights of PID Control include: an introduction to PID control technology features and typical industrial implementations; chapter contributions ordered by the increasing quality of the model information used; novel PID control concepts for multivariable processes. PID Control will be useful to industry-based engineers wanting a better understanding of what is involved in the steps to a new generation of PID controller techniques. Academics wishing to have a broader perspective of PID control research and development will find useful pedagogical material and research ideas in this text.
Download or read book Control Systems with Actuator Saturation written by Tingshu Hu and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Saturation nonlinearities are ubiquitous in engineering systems. In control systems, every physical actuator or sensor is subject to saturation owing to its maximum and minimum limits. A digital filter is subject to saturation if it is implemented in a finite word length format. Saturation nonlinearities are also purposely introduced into engineering systems such as control sys tems and neural network systems. Regardless of how saturation arises, the analysis and design of a system that contains saturation nonlinearities is an important problem. Not only is this problem theoretically challenging, but it is also practically imperative. This book intends to study control systems with actuator saturation in a systematic way. It will also present some related results on systems with state saturation or sensor saturation. Roughly speaking, there are two strategies for dealing with actuator sat uration. The first strategy is to neglect the saturation in the first stage of the control design process, and then to add some problem-specific schemes to deal with the adverse effects caused by saturation. These schemes, known as anti-windup schemes, are typically introduced using ad hoc modifications and extensive simulations. The basic idea behind these schemes is to intro duce additional feedbacks in such a way that the actuator stays properly within its limits. Most of these schemes lead to improved performance but poorly understood stability properties.
