Abstract: PID controllers are commonly used in many industrial control processes and seemed to be conducive to controlling a wide variety of real processes. In process control today, the majority of control loops are of the PID type. This controller applies and solves the majority of the problems of control. However, several complex processes namely: those with a non-minimal phase and/or complex poles, unstable processes, constrained or disrupted process proceed to a rigorous regulation of the coefficients respecting specified conditions and the use of advanced process controllers is essential. Dynamic matrix control is one of these advanced controllers and can solve this kind of systems. It refers to a class of control algorithms in which a process model is used to predict the behaviour of the process and optimise its performance. In this paper, some PID methods will be discussed and compared with the DMC for a disrupted complex process.
