Integral Sliding Mode Control with Exponential Reaching law for PMSM in Electric Vehicles

In electric vehicles (EV), control strategies play an important role in energy management and disturbance rejection. The studied electric vehicle traction chain in this article consists of a permanent-magnet synchronous motor (PMSM), an inverter and transmission. The proposed robust field oriented control strategy is based on integral sliding mode concept with exponential reaching law (ISMC-ERL). Unlike the conventional control techniques that lead to chattering effect, the adopted control scheme allows avoiding this drawback and ensuring a high performances, the ISMC-ERL allows also achieving high control performance in case of appearance of external load and parameter variations. Computer simulation using Matlab/Simulink environment have been carried out to evaluate the performance and the consistency of the proposed control approach.
