摘要
介绍了三相感应电动机单位功率因数运行的控制策略 ,以传递函数形式建立了电流环的数学模型和电压环的小信号数学模型 ,研制了以单片微处理机器为核心的数字模拟混合实验系统。该系统仅需两个电流传感器 ,且无需乘法器 ,从而使系统得以简化 。
The control strategy of 3-phase induction motor operation with unity power factor is introduced.The model of current loop and small signal model of voltage loop based on transfer function are set up.The experiment system based on digital and analog hybrid control is designed.The microprocessor is adopted in the experimental system as the central unit.Only two current sensors and no multipliers are required.So the system is very simple and practical.
