Passivity Based Control of Doubly Fed Induction Machine Using a Fuzzy Controller

In this paper, we are interested in the control of a Doubly Fed Induction Machine (DFIM) operating in motor mode. The proposed structure is based on the association of passivity and fuzzy control. The main objective of this configuration is to optimally regulate the motor speed according to variable references as well as tracking of the time-varying speed, the electromagnetic torque and the flux trajectories without a state observer. Simulation results showed remarkable efficiency in terms of stability and robustness of this structure with respect to parameter variations and disturbances. Results are compared with an existing work to show up the main points of our contribution.
