Sliding Mode Control Based on Exponential Reaching Law Applied on a Five-Phase Permanent Magnet Synchronous Generator Based Wind System

The present paper deals with the sliding mode control (SMC) based on the exponential reaching law (ERL) applied to a five-phase Permanent Magnet Synchronous Generator (PMSG) to overcome some problems faced while the application of the conventional sliding mode control and classical techniques like FOC or DTC. Despite, the three-phase PMSG has several advantage on the wind system; However, research has become increasingly interested on the five-phase PMSG due to offers additional degrees of freedom that can be used for fault-tolerant operation, very suitable for high power, high reliability and low dc bus voltage applications. As regards the SMC based on ERL control has several benefits that you didn’t check the controls mentioned above, where it gives good characteristics performance, it is robust control under the variation parameters or disturbances. In adding, it contributed to reduce the chattering. The obtained results by simulation prove the validity of the application of SMC based on ERL for ensuring a robust control of the studied five-phase PMSG with higher performance compared to the conventional control techniques mentioned above‏.
