Available in PDF, EPUB and Kindle. Book excerpt: The sliding mode controller is one of the interesting classical nonlinear controllers in structural vibration control. From its apparition, in the middle of the twentieth century, this controller was a subject of several studies and investigations. This controller was widely used in the control of various semi-active or active devices in the civil engineering area. Nevertheless, the sliding mode controller offered a low sensitivity to the uncertainties or the system condition variations despite the presence of the Chattering defect. However, the adaptation law is one of the frequently used solutions to overcome this phenomenon offering the possibility to adapt the controller parameters according to the system variations and keeping the stability of the whole system assured. The chapter provides a sliding mode controller design reinforced by an adaptive law to control the desired state of an excited system. The performance of the adaptive controller is proved by numerical simulation results of a three-story excited structure.

Download or read book Adaptive Sliding Surface Design for Sliding Mode Control Systems written by Nurdan Bekiroğlu and published by . This book was released on 1996 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many cases, the available information for dynamic modeling of a physical system, is not sufficient. Since modeling inaccuracies and disturbances can cause some adverse effects on control systems, any practical design must consider them. There are mainly four approaches to control uncertain systems: adaptive control, robust control and their combinations in two different ways, namely robust adaptive control (RAC) and adaptive robust control (ARC). This thesis deals with adaptive sliding mode control (ASMC) which is an important type of ARC. sliding mode control (SMC), most of the sliding surfaces proposed so far have been determined without considering the non-zero initial tracking errors. Therefore sliding mode starts after a reaching period which has some problems related to the tracking performance, the robustness property and the control inputs. Although there exist certain approaches to reduce or eliminate the reaching period of SMC and thus the corresponding problems, these approaches have some drawbacks which form the problem statement of this thesis. In this thesis, using some concepts from model reference adaptive control (MRAC) theory, both linear and nonlinear versions of an adaptive sliding surface (ADSS) design, are proposed for the sliding mode control of uncertain nonlinear systems. In the ADSS approach, the constant parameters of the conventional sliding surface are replaced by the parameters which are updated by an adaptation algorithm. This adaptation algorithm forces the tracking errors of the system to follow the behaviors of appropriate reference error models. It is possible in ADSS to reduce the distance between the non-zero initial tracking errors and the sliding surface since these tracking errors are considered while choosing the initial values of the updated sliding surface parameters. Therefore the ADSS approach reduces the reaching period and thus improves the robustness property and the tracking performance of the system without causing the chattering problem, without using very large control inputs and without making some restrictive assumptions. It is expected that ADSS will be suitable in various practical applications since it is simple in structure; it is applicable to a large class of uncertain multi-input nonlinear systems and it is able to complement various SMC or adaptive SMC algorithms as shown in this thesis.

Download or read book Sliding Mode Control in Electro Mechanical Systems written by Vadim Utkin and published by CRC Press. This book was released on 2017-12-19 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: Apply Sliding Mode Theory to Solve Control Problems Interest in SMC has grown rapidly since the first edition of this book was published. This second edition includes new results that have been achieved in SMC throughout the past decade relating to both control design methodology and applications. In that time, Sliding Mode Control (SMC) has continued to gain increasing importance as a universal design tool for the robust control of linear and nonlinear electro-mechanical systems. Its strengths result from its simple, flexible, and highly cost-effective approach to design and implementation. Most importantly, SMC promotes inherent order reduction and allows for the direct incorporation of robustness against system uncertainties and disturbances. These qualities lead to dramatic improvements in stability and help enable the design of high-performance control systems at low cost. Written by three of the most respected experts in the field, including one of its originators, this updated edition of Sliding Mode Control in Electro-Mechanical Systems reflects developments in the field over the past decade. It builds on the solid fundamentals presented in the first edition to promote a deeper understanding of the conventional SMC methodology, and it examines new design principles in order to broaden the application potential of SMC. SMC is particularly useful for the design of electromechanical systems because of its discontinuous structure. In fact, where the hardware of many electromechanical systems (such as electric motors) prescribes discontinuous inputs, SMC becomes the natural choice for direct implementation. This book provides a unique combination of theory, implementation issues, and examples of real-life applications reflective of the authors’ own industry-leading work in the development of robotics, automobiles, and other technological breakthroughs.

Download or read book Discrete time Sliding Mode Control written by B. Bandyopadhyay and published by Springer Science & Business Media. This book was released on 2005-10-17 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sliding mode control is a simple and yet robust control technique, where the system states are made to confine to a selected subset. With the increasing use of computers and discrete-time samplers in controller implementation in the recent past, discrete-time systems and computer based control have become important topics. This monograph presents an output feedback sliding mode control philosophy which can be applied to almost all controllable and observable systems, while at the same time being simple enough as not to tax the computer too much. It is shown that the solution can be found in the synergy of the multirate output sampling concept and the concept of discrete-time sliding mode control.

This book was released on 2011 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Structural control technologies have been widely accepted as effective ways to protect structures against seismic and wind hazards. Sliding mode control (SMC) is among the popular approaches for control of systems, especially for unknown linear and nonlinear civil structures. Compared with other control approaches, sliding mode control is invariant to disturbance such as wind and earthquake, and to system parameters such as the mass, stiffness, and damping ratio matrices if the uncertainties can be represented the linear combination of the control input, which is generally satisfied for most civil structures.

Download or read book Active Control of Bidirectional Structural Vibration written by Wen Yu and published by Springer Nature. This book was released on 2020-06-05 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on safeguarding civil structures and residents from natural hazards such as earthquakes through the use of active control. It proposes novel proportional-derivative (PD) and proportional-integral-derivative (PID) controllers, as well as discrete-time sliding mode controllers (DSMCs) for the vibration control of structures involving nonlinearities. Fuzzy logic techniques are used to compensate for nonlinearities. The first part of the book addresses modelling and feedback control in inelastic structures and presents a design for PD/PID controllers. In the second part, classical PD/PID and type-2 fuzzy control techniques are combined to compensate for uncertainties in the structures of buildings. The methodology for tuning the gains of PD/PID is obtained using Lyapunov stability theory, and the system’s stability is verified. Lastly, the book puts forward a DSMC design that does not require system parameters, allowing it to be more flexibly applied. All program codes used in the paper are presented in a MATLAB®/Simulink® environment. Given its scope, the book will be of interest to mechanical and civil engineers, and to advanced undergraduate and graduate engineering students in the areas of structural engineering, structural vibration, and advanced control.

Download or read book Model Predictive Vibration Control written by Gergely Takács and published by Springer Science & Business Media. This book was released on 2012-03-14 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time model predictive controller (MPC) implementation in active vibration control (AVC) is often rendered difficult by fast sampling speeds and extensive actuator-deformation asymmetry. If the control of lightly damped mechanical structures is assumed, the region of attraction containing the set of allowable initial conditions requires a large prediction horizon, making the already computationally demanding on-line process even more complex. Model Predictive Vibration Control provides insight into the predictive control of lightly damped vibrating structures by exploring computationally efficient algorithms which are capable of low frequency vibration control with guaranteed stability and constraint feasibility. In addition to a theoretical primer on active vibration damping and model predictive control, Model Predictive Vibration Control provides a guide through the necessary steps in understanding the founding ideas of predictive control applied in AVC such as: · the implementation of computationally efficient algorithms · control strategies in simulation and experiment and · typical hardware requirements for piezoceramics actuated smart structures. The use of a simple laboratory model and inclusion of over 170 illustrations provides readers with clear and methodical explanations, making Model Predictive Vibration Control the ideal support material for graduates, researchers and industrial practitioners with an interest in efficient predictive control to be utilized in active vibration attenuation.
