Design of a Performance-Adaptive PID Controller Based on IMC Tuning Scheme
نویسندگان
چکیده
PID control schemes have been widely used in most process control systems for a long time. However, it is a very important problem how to choose PID parameters. Because these parameters give a great in uence on the control performance. Especially, it is dif cult to tune these parameters for time-varying systems. In this paper, performance adaptive controller is proposed for such systems, which is based on the IMC tuning scheme. It is well known that the IMC tuning method includes a user-speci ed parameter. According to this scheme, the user-speci ed parameter can be adjusted based on control performance.

متن کاملExtension of IMC tuning correlations for non-self regulating (integrating) processes.
The filter term of a PID with Filter controller reduces the impact of measurement noise on the derivative action of the controller. This impact is quantified by the controller output travel defined as the total movement of the controller output per unit time. Decreasing controller output travel is important to reduce wear in the final control element. Internal Model Control (IMC) tuning correla...
