CONSTRAINED PREDICTIVE CONTROL FOR POSITION TRACKING OF AN INDUCTION MOTOR

摘要

The receding horizon strategy can successfully control an industrial positioning system demanding high-performances. The most important difficulties rise when handling constraints imposed by the physical limitations or stability requirements. In the present paper, such a predictive strategy in a constrained framework is analyzed. Further the time-consuming on-line constrained optimization is avoided by means of an off-line computed linear law, whose limitations are adapted on-line. The linear dependence of the limitations on the context parameters is detailed and the linear expression of the adaptation mechanism is found.
