Abstract

This paper mainly deals with the design of an advanced control law for induction motors and its real-time implementation on an experimental test benchmark. First, relationship between the classical field oriented control (FOC) and non linear linearizing control laws is studied. It is shown that both control laws are similar. Classical non linear linearizing control improves the performances but not in a spectacular way when the observer and the controller are designed independently. A new non linear observer based control law is designed, which is shown to be globally stable and is implemented on an experimental test-bench. The control algorithm is studied and applied in many configurations (various set-points, flux and speed profiles and torque disturbances) and is shown to be very efficient.
