IMC-PID Design Based on an Approximation of Polynomial Equations
In this study, we propose a method of designing IMC-PID based on approximation of polynomial equations. In the industrial field, IMC-PID is used by many engineers, because it has a good robustness and a good performance. However, the design of the conventional IMC-PID controller is complex. To solve this problem, in this paper, we design IMC-PID controller by using polynomial equations approximation. Our simulation results show that the proposed method has a better performance than that of the conventional IMC-PID.
