Abstract
On the basis of a novel dynamic model obtained under a special non-linear co-ordinate transform on a d–q-axis model (w.r.t. the stationary reference frame) of an induction motor, a simple but effective control law for speed regulation is proposed in this paper. This controller is designed using the concept of the field orientation and the property of linear PI-controller, and is shown to be robust with respect to variation of system parameters and load structure. To be rigorous, a Lyapunov theorem with a simple iterative criterion derived in this paper proves the local exponential stability of the system around any desired speed. Numerical simulations are also given to show the effectiveness of the presented control law. Copyright © 2000 John Wiley & Sons, Ltd.
