单周期控制直流电机双闭环调速系统设计

Double Loop DC Speed Regulation System Design Based on OCC

阐述了单周期控制(OCC)PWM的方法在直流电动机调速中的应用。OCC调节电流环作为内环,PID调节速度环作为外环。通过分析和计算设计出了控制电路。实际调试证明,这种控制电路在未知电动机数学模型的前提下,具有电动机转速无静差、动态响应快、电流环参数无需调节的特点。

Elaborated on the method of one cycle control （0CC） PWM used on DC speed regulation. The control circuits are designed based on analysis and calculations. Verified by actual debugging, when mathematical model of DC motor is uncertain, the circuits have features such as no speed static error, rapid dynamic response, no need to adjust current loop parameters.
