Cascaded model predictive position control of induction motor with constraints

In this paper, position control of induction motor is addressed by using a continuous-time Model Predictive Control (MPC) algorithm. The control system is designed based on the indirect vector control technique and the cascaded control structure with two MPC controllers is proposed. The operational constraints are imposed on the currents, which provides safety protection for the control system. The exponential data weighing technique used in MPC design is deployed for obtaining a fast inner-loop dynamic response and a slow outer loop response. The proposed predictive position control has been evaluated on an induction motor test bed, coupled with an DC servo motor as a load.
