Application of Nonlinear Sliding-Mode Control to Permanent Magnet Synchronous Machine: (Study of the robustness)

This article is devoted to the study of the performances of the nonlinear order by sliding-mode with the integration of an integrator regulator, applied to the synchronous permanent magnet machine. In a first stage, we presented the design of the order by this new approach followed by a structure of the optimal ordering of the adjustment with the law of commutation against reaction of state with integrator. The second stage is devoted to the development of an order to variable structure with a strategy of three surfaces, which allow the elimination of the overloads that can result in a destruction of the system to regulate.
