Sliding mode control applied to the inner loop regulation of a faulted six phase induction machine (6PIM)

In this paper, sliding mode control (SMC) is applied to regulate the dq axis currents of a 6 phase induction machine (6PIM). This strategy presents a good alternative in power electronics for electrical drives because of its dynamic properties and its high robustness. The design of the sliding mode control law, defined from the healthy mode model, is based on the linear feedback with switched gains approach. With this strategy, the control voltages are smooth and guarantee the stability of the control loop regarding the faulted condition of the 6PIM. Experimental results assess the robustness of the proposed sliding mode control compared to traditional Proportional-Integral algorithm.
