A test bench composed by induction motor and dc motor is proposed to test the performance of power source on EVs. The test bench is a complex electromechanical coupling system with mechanical, electrical and magnet fields. The electromechanical coupling model of the system was built. The nonlinear system was linearized with the help of α order integration inverse system. The adaptive fuzzy neural network control was applied to the system based on the inverse system control. That also leads to a better decoupling simulation and experimental results. Both of the feedback of AC motor speed and DC motor torque follow the targets. The variations of voltage, current and power on the DC bus of the battery connected with induction motor can be observed, which provides the theoretical foundation for the research on the hybrid energy storage system.
