On-line identification research of pneumatic servo control system

摘要：

Because of strong nonlinearity and low stiffness of pneumatic servo control system , modern control theory and intelligent control theory are mainly used in pneumatic servo control system,so there should be on-line identification to estimate system parameter. In this paper, Recursive Forgetting Factor Method and are used in the on-line identification research of pneumatic position servo control system which adopts pole-placement adaptive control method, and contrast between Recursive Forgetting Factor Method on-line identifidation result and Amendatory Square-root Method on-line identifidation result had been analysed mainly, furthermore, controlling results of pneumatic position servo control system from the two different identification methods have been contrasted, too. The experiment shows Amendatory Square-root Method works well with the pneumatic position servo control system adopting pole-placement adaptive control method.
