Using the method of on-line identification of iron loss resistance,establish the parameter analysis model of vehicle electrical traction system control,solve the parameter information of iron loss resistance,establish the motor mathematical model of vehicle electrical traction system,establish the steady-state analysis model of vehicle electrical traction system through the coupling control method of flux and torque,and then analyze the steady-state and dynamic performance of the system,Realize the impedance adjustment of synchronous reluctance motor,and realize the optimal design of vehicle electrical traction system control law according to the parameter adaptive adjustment results. The test results show that the adaptive performance of vehicle electrical traction system control using this method is good,the steady-state adjustment ability of parameters is strong,and the control ability of vehicle electrical traction system is improved.
