利用PWM驱动方式控制电机的转动,并设计出了直流伺服控制系统硬件电路图。
Using PWM to drive motor, and we design a circuit in DC serve control system.
试验表明,该系统可以获得不同缺陷电容器发生局部放电时放电幅值的时间分布谱图,这为直流局部放电的统计分析和模式识别、判断故障类型和介质老化程度打下了良好的基础。
Through the experiments, the magnitude of PD over time in different capacitors were got, which would be used to recognize the PD patterns and to determine fault types and aging degree.
