Real-Time Hybrid Control of Induction Motor Using Sliding Mode and PI Anti-Windup

This paper presents a combined hybrid command between the sliding mode and PI Anti-Windup applied for the speed pursuit of an induction motor, the nonlinearity of their mathematical model increases the conception complexity of a powerful controller, the conventional methods cannot guarantee good performances in the presence of structural or external disturbances. The advantage of using sliding mode control is the simplicity of the design and their insensitivity to parametric variations. But the chattering phenomenon appeared in the steady-state remains an obstacle limits the application of this technique. We proposed to use a PI Anti-Windup regulator for control in the steady-state, however, the sliding mode regulator will work during the transient regimes, where a classical supervisor can handle the transition from one controller to another via approximate information on the operating regime. Experimental results are presented and analyzed to justify the effectiveness of the proposed approach.
