Abstract

A simple modified Smith predictor controller design is proposed for integrating processes with long dead-time. The overall control structure introduce two physically meaningful tuning parameters. One is used to set the speed of the closed-loop servo response and the other is used to set the performance of the load response. A simple controller tuning method is also developed to obtain the PI tuning parameters. With a given estimation of the uncertainty bound of the dead-time, the stability region of the tuning parameter can be estimated .Two examples are used to demonstrate the improved closed-loop performance of the proposed controller design
