The drive system is one of the key technologies for electric vehicle. The electric vehicle performance was improved using the discrete-time model reference adaptive control methods to the driven motor. The discrete-time model of EV driven motor was proposed, and the reference model was founded according to the performance target offered. Based on it, the design of the adaptive control was made,
... [Show full abstract] and the rule of discrete-time model reference adaptive control was proved. The studies of simulation show that the model reference adaptive control system has better performance than the PID control system. The results of experiment attest to the feasibility of the design.
