Abstract

Model predictive control (MPC) is one of the widely used concepts in the control engineering practice and in real-time applications. Generalised predictive control (GPC) is one of the most popular among the types of MPC. Because of its desirable features, it has become a popular tool for the control of most of the processes. However, there are certain limitations which restrict the use of GPC. In this paper, in addition to the basic concept of GPC, control law formulation, advantages and disadvantages, the other techniques that make use of constraints, continuous-time approach, providing delay, selecting sampled data and rate, use of delta operator, intelligent controllers, min–max techniques with GPC which overcome the limitations of traditional GPC have been discussed. The review on GPC technique and its advances has been presented in this paper.
