Abstract: The design of control system for low-voltage asynchronous motor used in EPS was introduced.The principle of controlling lowvoltage asynchronous motor was analyzed and the system about how to control low-voltage asynchronous motor had been designed.The hardware and the software flow of the control system were presented in detail and used the Freescale’s DSP56F8346 as CPU.Experimental results certified the feasibility of the control system.As there is no literature concerning lowvoltage asynchronous motor control system used in EPS domestic and international,it has some value for reference.
