DI Jing, ZHANG Shen, FAN Ti feng (College of Information and Electrical Engineering, CUMT., Xuzhou 221008, China)
A control method of DC motor using phase locked loop (PLL) was analyzed. The combination model of DC motor and optic coupler was given. According the model, a PLL structure for DC motor control system was designed and the characteristic of the system was measured. A linear control characteristic at the range of 50～2400Hz was obtained.
