Anti‐saturation GPC speed control of induction motor drives
Abstract One of the most critical issues in the fast and large step change in the speed control of an induction motor is the excessive generated current command, and consequently, if the speed controller does not have output magnitude limiter, this might end up damaging the power electronics convert...

| description | Abstract One of the most critical issues in the fast and large step change in the speed control of an induction motor is the excessive generated current command, and consequently, if the speed controller does not have output magnitude limiter, this might end up damaging the power electronics converter and the motor itself. This paper is devoted to overcoming the speed controller saturation phenomenon. Firstly, predictive controllers in polynomial form are designed for the speed control loop and for the two inner currents control loops. Then, the outer predictive speed controller is retuned by convex optimization of the Youla parameter considering temporal and frequency constraints, so that the resulting controller assures that the speed response to the reference remains in an imposed template with a minimal current command in transient periods and, in other hand, it keeps the closed loop features obtained by the initial predictive controller. Simulations results show the speed control performance of the proposed control system for various operating conditions of the motor. |
