Robust nonlinear receding horizon control of permanent magnet synchronous machine

Abstract

This paper deals with robust nonlinear speed control of permanent magnet synchronous machine. The controller is based on one-step-ahead continuous time minimization of the predicted tracking error and no online optimization is required. An integral action is incorporated in the loop to increase the robustness of this control scheme against load torque variations. The proposed nonlinear controller permits to achieve asymptotic speed tracking in presence of unknown load torque and resistance variations. Simulations are performed to validate the tracking performance of the proposed controller.
