Backstepping fuzzy adaptive controller of induction machine

In this paper, the design of a backstepping adaptive fuzzy controller for induction machine is addressed. The backstepping has been adopted to exploit the field oriented control scheme and to use only one control channel. Thus, the true and virtual control signals have been synthesized, using two adaptive fuzzy systems, to overcome the constraint on the well knowledge of the machine parameters. These adaptive fuzzy systems will be adjusted on-line according to some adaptation law deduced from the stability analysis in the sense of Lyapunov. Simulation results are provided to demonstrate the effectiveness of the proposed approach.
