Semi-physical real-time control of electro-hydraulic proportional position servo system based on Matlab/xPC

Abstract

A set of semi-physical simulation system based on real-time working simulation platform tools (Matlab/RTW) was established for electro-hydraulic proportional position servo system in the development of missile weapons and other equipment. The system is mainly composed of hydraulic system consisting of hydraulic actuators and Simulink simulation model. It is a closed-loop real-time simulation system of physical equipment in the loop. The simulation and experiment of proportional servo control system show that the system has high simulation real-time performance, the positioning accuracy and control stability. Two controllers are designed for different application conditions, which can obtain the good practicality and feasibility.
