Predictive controller design with the guaranteed H∞ control performances for electrical drives.

Generalized Predictive control GPC techniques represent an efficient approach to the control of a large number of industrial plants. The basic idea of these methods, is to compute series of control vectors in order to impose to the system output the desired trajectory tracking. Then, only the first control vector is used and, the computing is reinitialized at each sampling period. However, The control method do not enable to say a priori the stability of the closed-loop system, for a particular choice of the design parameters. So, it is important to elaborate a procedure for the determination of the parameters control when the GPC is applied on an industrial system. The authors present in this paper their studies on the predictive control applied on electrical machine drives. Moreover, in order to evaluate the performances of controlled system, they use the robustness notions on the sensitivity functions introduced by Morari. These results have been applied on a DC motor system. The most interesting simulation results of this control design are presented.
