A study putational simulations for electro-hydraulic proportional position control system based on hybrid reference model adaptive robust control strategies
Abstract: This paper introduces the basic conception of automatic control, and the use of MATLAB and simulation toolbox Simulink in this thesis, and introduces the basic conception, development course and the technique of electro-hydraulic proportional control. The function of this technique is between serve system and switch, the characteristics of it are cheap, energy-saving, easy maintenance, preferable control precision and response characteristic. It is about the study of position control in electro-hydraulic proportional control. One is the design of electro-hydraulic proportional control system, and the other is the research of control strategy. Give a systematic design to the electro-hydraulic proportional hydraulic system controlled puter. Finally a simulation scheme of this hydraulic system is given. And the following is the model building of this system. The emphasis of the paper deduces the control algorithm of model reference adaptive robust control and put up putational simulation. Also there parisons and analysis for the simulation result of various control algorithm, it gives a few primary c
