IMC based PID Controllers Retuning and It's Performance Assessment

摘要

Internal Model Control (IMC) is the basis of a systematic program Q on the parameters of the concept and is based on the many modern control technology control system design. What makes IMC particularly attractive is that it presents a method to design the Q-parameterization controller has two basic demands of reality. Therefore, IMC has been a popular design process processing industry, especially as a means for adjusting the single-loop, PID controllers. In this paper, we propose an optimal filter design IMC IMC-PID controller for unstable process better set point tracking. The controller is suitable for different values of the filter tuning parameters to achieve the desired response in due IMC method is based on pole-zero offset, including IMC design principle method causes the response sets a good point. However, in a stable long lag time of load disturbances leading to undesirable process which is the result of the IMC control industry. [1]
