The Control Policy And Application Of The Cylinder Position Control System

Pneumatic technology has a series of obvious advantages such as low cost, simple construction, reliable in work,no air pollution. ,So it is applied widely in industry more and more,and becomes an important method of automation.However,the inherent characteristics of the pneumatic system, such as the condensability of the air, friction characteristic of pneumatic cylinder, nonlinear of valve and easily influenced by environment factors, greatly increased the control difficulty in a degree, and is hard to satisfy the orientation request in industry."The Control Policy and Application of the Cylinder Position Control System"is part of the international cooperation programs in SMC–SJTU technology Center .The goal is to build Ball&Plate control system based on pneumatic actuated for laying out the performance of the pneumatic components, also for the course of control theory for undergraduate.A common pneumatic cylinder, MQQTB16-50D of SMC company,is selected as the actuator, but it's difficult to carry out servo control because of...
