Abstract
Over decades, dynamic matrix control (DMC) was used as an advanced control strategy in processing industries that yields good performance, especially in the presence of uncertainties and undesirable noises. As the implementation of PID algorithm in digital platform is easier, an equivalent PID controller is synthesized where proportional gain (KC) of a controller is obtained by approximating a dynamic matrix control algorithm. Integral time (?i) and derivative time (?d) are obtained from process model and step response coefficients. The performances of the equivalent PID controller are tested on different process models (dynamics) and closed loop responses are analyzed. This performance is compared with the DMC-SISO response. The designed PID controller is robust and stable. Results obtained from a computer simulation are presented.
