摘　　要：分析了锁相环路直流电机转速控制方案 ,给出了电机与光电耦合器在锁相环路中的组合模型。根据此组合模型设计了锁相环路结构 ,并对锁相直流电机控制系统进行了测试 ,结果表明在 5 0～ 2 4 0 0Hz范围内可进行精确的线性控制。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.
