Winter Annual Meeting and published by . This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic oscillators, with their high torque output, have been widely used in many applications. To increase the position control accuracy of electrohydraulic servo-valve controlled oscillators, Model-Flowing Optimal Control Techniques are employed for the controller design in this study. Different reference models, which are followed by the oscillator for positioning, are chosen and implemented.

Based on the on-line system parameters, the optimal controller generates time-variant feedback gains, and makes the control system possess the ability of real-time adaptation.

Available in PDF, EPUB and Kindle. Book excerpt: Applied Control System Design examines several methods for building up systems models based on real experimental data from typical industrial processes and incorporating system identification techniques. The text takes a comparative approach to the models derived in this way judging their suitability for use in different systems and under different operational circumstances. A broad spectrum of control methods including various forms of filtering, feedback and feedforward control is applied to the models and the guidelines derived from the closed-loop responses are then composed into a concrete self-tested recipe to serve as a check-list for industrial engineers or control designers. System identification and control design are given equal weight in model derivation and testing to reflect their equality of importance in the proper design and optimization of high-performance control systems. Readers’ assimilation of the material discussed is assisted by the provision of problems and examples. Most of these exercises use MATLAB® to make computation and visualization more straightforward. Applied Control System Design will be of interest to academic researchers for its comparison of different systems models and their response to different control methods and will assist graduate students in learning the practical necessities of advanced control system design. The consistent reference to real systems coupled with self-learning tools will assist control practitioners who wish to keep up to date with the latest control design ideas.

This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic servo mechanisms combine hydraulic power and feedback techniques to achieve rapid, accurate regulation. In recent years with the development of electronic technology, electro-hydraulic servo control systems have found more usage in industry and military systems of all types. This thesis deals with the mathematical modelling and computer simulation of an electro-hydraulic servovalve controlled motor for both speed and position schemes. As a preliminary investigation, these systems are simplified to achieve insight into the physical problem. In the speed control scheme, linear equations are employed to describe the system. However in the position control scheme, the equations describing the system are nonlinear. Control theory is used to analyse the system and thereafter simulation programs for both speed control and position control are designed to investigate dynamic behaviour and simulated results of each system are shown graphically. Some improved control concepsions are also given in this thesis. In speed control scheme, a slope command signal is utilised instead of a sudden change of command signal, and this improvement achieves the reduction of the system overshoot and oscillation. In position control, which is a variable torque system, so called 'equigain' and 'varigain' control schemes are established to improve the accuracy of trajectory control. Finally recommendations for further work are presented with references for initiating these enquires.

This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is concerned with the practical application of Model Reference Adaptive control (MRAC) on the position control of a hydraulic cylinder. In this study, the modified hyper-stable MRAC method is employed to adapt loading effect. The reference model is based on the reduced-order model of the plant, which is derived by suing the Routh stability criterion and the Pade approximation technique. A 16-bit microcomputer is used to design an adaptive controller. The experimental results are also compared with those obtained by using the classical control theory.

Download or read book Modeling Analysis and Control of Hydraulic Actuator for Forging written by Xinjiang Lu and published by Springer. This book was released on 2017-12-30 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes load modeling approaches for complex work pieces and batch forgings, and demonstrates analytical modeling and data-driven modeling approaches for known and unknown complex forging processes. It overcomes the current shortcomings of modeling, analysis and control approaches, presenting contributions in three major areas: In the first, several novel modeling approaches are proposed: a process/shape-decomposition modeling method to help estimate the deformation force; an online probabilistic learning machine for the modeling of batch forging processes; and several data-driven identification and modeling approaches for unknown forging processes under different work conditions. The second area develops model-based dynamic analysis methods to derive the conditions of stability and creep. Lastly, several novel intelligent control methods are proposed for complex forging processes. One of the most serious problems in forging forming involves the inaccurate forging conditions, velocity and position offered by the hydraulic actuator due to the complexity of both the deformation process of the metal work piece and the motion process of the hydraulic actuator. The book summarizes the current weaknesses of modeling, analysis and control approaches. are summarized as follows: a) With the current modeling approaches it is difficult to model complex forging processes with unknown parameters, as they only model the dynamics in local working areas but do not effectively model unknown nonlinear systems across multiple working areas; further, they do not take the batch forging process into account, let alone its distribution modeling. b) All previous dynamic analysis studies simplify the forging system to having a single-frequency pressure fluctuation and neglect the influences of non-linear load force. Further, they fail to take the flow equation in both valves and cylinders into account. c) Conventional control approaches only consider the linear deformation force and pay no attention to sudden changes and the motion synchronization for the multi-cylinder system, making them less effective for complex, nonlinear time-varying forging processes subject to sudden changes.
