To improve the synchronization performance for the double variable leakage flux permanent magnet (VLFPM) motors drive control system of electric vehicles (EVs), this article presents sensorless cooperative drive control strategies from the perspective of sensorless control and cooperative control. Due to the variable saliency characteristics and complex harmonics interference of the VLFPM motor, the estimation accuracy of the rotor position with the conventional sensorless will be greatly reduced. Hence, the rotor position observation and harmonics suppression methods are designed by a third-order linear extended state observer (LESO) and state compensator in this article. Furthermore, for improving the dynamic and steady-state performance of sensorless cooperative control, the sliding mode control (SMC) with a novel variable-speed exponential reaching law (VSERL) is proposed to optimize the cross-coupling control structure. Therefore, the proposed algorithms for the dual VLFPM motor drive control system have good estimation performance at low-speed regions, strong robustness to motor parameters and load disturbance, and good synchronization performance under different operating conditions. The experimental results verify the feasibility and effectiveness of the proposed double VLFPM motors sensorless cooperative drive control strategy.
