Abstract

A new approach to dynamic feedback linearization control of an induction motor is given. Previously, it has been shown that the dynamic model of an induction motor consisting of speed, stator currents and rotor flux is dynamically feedback linearizable. However, the controller and transformation were valid only as long as the motor torque was nonzero and the methodology required switching between two computationally complex transformations. Here it is shown that, by considering the direct-quadrature model of the induction motor, a single dynamic feedback linearizing transformation exists and is valid as long as the (magnitude of the) rotor flux is nonzero. Furthermore, the resulting control computations are well within the capabilities of contemporary microprocessor technology
