A new control strategy for induction motor based on linear predictive control with constraints

摘要

A constrained generalized predictive control (GPC) algorithm is presented for the non linear system. Generalized predictive control methods are gaining widespread acceptance industry-as they offer good performance based on simple step response or transfer -function which can be obtained experimentally a GPC. In this paper we are illustrated the GPC without constraint and output constrained controller to induction motor drive. The variable to be controlled are the rotor speed and flux trajectory. The load torque is considered as unknown disturbance. The simulation results show a good performance for the non linear systems.
