Abstract
The predictive control is born of a real need in the industry. A need for systems capable of regulating higher performance than conventional controllers (PID), while respecting the constraints of operation and producing even higher. Many predictive control algorithms have been developed and their differences are based on the types of prediction model used to represent the process, the noise and the performance function to be minimized. In this paper the generalized predictive control (GPC) is used on the induction machine for speed control. The philosophy of this command is based on four main ideas reproducing the basic decision-making mechanisms of human behavior: Creating an anticipatory effect by exploiting the path to follow in the future definition of a numerical model prediction, minimizating of a quadratic criterion with finite horizon. We present in this paper a comparative study between two control strategy of electrical machines for controlling the speed The comparison is based on several criteria including: static and dynamic performance, structure and implementation complexity, Also, we present in this study the advantages and disadvantages of each control scheme, the best is the one that better meets the requirements.
