Toward an optimal twisting-sliding mode control of a three-phase PMSM for electric vehicles

This paper deals with an optimal twisting sliding mode controller (OT-SMC) for the operation of a three phase permanent magnet synchronous machine (PMSM) in electric vehicle (EV). In order to drive these vehicles, performance is needed robust control against real-time disturbances such as variable load torque, uncertainties parameters variation and speed variations between medium, low, high well good characteristics enhanced quality longer battery time. Several conventional techniques have been applied PMSM but they suffer from problem due PI regulator. A hybrid approach comprising nonlinear achieve objectives attempted driving electrical vehicles. advanced obtained after merger (SMC) linear quadratic (LQR) found outperform existing controllers their superb characteristics. Furthermore, SMC designed based on exponential reaching law (T-SMC) ensure stability system while reducing chattering, accelerating rate convergence higher accuracy performance, LQR developed using steady-state error method (N-LQR) obtaining better addition, hybridization characterized by stabilizing minimizing oscillations regime thus optimizing system’s performance. Extensive simulation results illustrate effectiveness validity proposed achieving highest PMSM.
