Position predictive control for an induction motor

This paper presents a position predictive control scheme for an induction motor. The non-linear differential equations, which describe the dynamics of the motor, are represented by a d-q model. The design of a Generalised Predictive Control is obtained as a simplified model. On the other hand, an observer is used in open loop in order to obtain state measurements. The main advantages offered by the proposed scheme are: the position is the only measurement required and the simplicity of the control law allows a simple and straightforward implementation. The efficiency of the controller is demonstrated through simulations.
