Constrained Receding Horizon Predictive Control For Position Tracking Of A Induction Motor

Abstract

The receding horizon strategy can successfully manage controlling 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, the feasibility analysis for the optimal control sequence will be used as a tuning procedure for the predictive strategy. 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.
