Abstract

A novel pneumatic position servo system is described, in which an electro-pneumatic converter is a 2-way-3-port electro-pneumatic pressure valve. On the basis of analyzing and studying the pneumatic position servo system, a new control method which improves the system performances by means of an adaptive variable gain optimal control is presented for the weak point of the pneumatic position servo system. Theoretical analysis and experimental research show that the cost of the novel pneumatic position servo system is decreased largely. The control algorithm is easy to be implemented online. The method also improves the damping and responsive characteristics of the pneumatic position servo system
