High-performance induction motor speed control using exact feedback linearization with state and state derivative feedback

This paper presents a novel nonlinear speed/position control method for the induction motor utilizing exact feedback linearization with state and state derivative feedback. The control scheme is derived in rotor field coordinates and employs an appropriate estimator for the estimation of the rotor flux angle, flux magnitude, and their derivatives. An error sensitivity analysis is included. Simulation and experimental results validate the theoretical part of the paper and reveal the high performance and advantages of the novel control scheme.
