Abstract :
In this paper, a new IMC-based PID controller design is proposed. The model reduction is employed to find the best PID controller approximation to the IMC controller. Compared with the existing IMC-based methods, the proposed design is applicable to a wider range of processes, and yields a control system with performance closer to the more sophisticated IMC counterpart. Furthermore, it can be made automatic for on-line tuning. And this design procedure can be readily extended to MIMO systems.
