Feedback Filter PID Control for Integrator and Time Delay Processes

Abstract:

A PID controller based on a typical feedback model is introduced because of instability of a kind of integrator and time delay process on open-loop condition. All-pole-type approximating method is adopted to deal with delay part of the controlled object approximately,and confirmed parameters of PID controller is obtained by importing a strategy of confirming parameters of PID controller based on a kind of typical feedback model from IMC principle.The designed control method shows better set point tracking performance based on initialed parameters point and better interference suppression performance of the controlled object.The structure of the controller is simple, and parameters are easy to adjust, the improved controller is easy to apply to practical projects.The simulation results show its effectiveness
