The Study Of Real-time Control And Advanced Control Technology Of Electro-hydraulic Servo System

Electro-hydraulic Servo System has good agility and adaptability because it can exert the merits of electron and hydraulic pressure. It applies very broadly in mechanism of manufacture, shipping manipulation and industry process controller. Electro-hydraulic servo flight simulator is absolutely necessarily key equipment in developing inertia navigation system. So it is very important that studying the real-time control and advanced control method of Electro-hydraulic Servo System.Firstly, this thesis summarizes the configuration, classification, advantages, disadvantages and specifications of Electro-hydraulic Servo System. Secondly, it analyse the mathematics model of hydraulic pressure loop, the hardware and software design of the turntable simulator. Meanwhile, it mainly focuses on the control system and the typical digital-rectify network implementation. Furthermore, by analyzing the problem of non-linearity and low-velocity, the corresponding avoid approaches are discussed and an adaptive friction compensation method using the RBF network is put forwarded. Finally the real time control techniques based on Windows platform are discussed particularly and applications can interrupt real time based on Windows platform.
