High performance nonlinear controller design for AC and DC machines: partial feedback linearization approach

Abstract

This paper presents the design of a partial feedback linearization controller for speed control of DC and AC machines. The design of the controller is presented based on the nonlinear modeling of the plant. The model of the plant is obtained from differential dynamic equations. A stability analysis is presented to guarantee the stability of the proposed design. To validate the effectiveness of the controller, DC and AC machines systems are simulated. The performance of proposed controller is investigated with respect to different amount of load torque. Simulation studies show that the proposed controller provides the accuracy and high performance for both AC and DC machines.
