基于旋转变压器的永磁同步电机转子位置估计

代码说明：

说明：  提出了方波激励方法和信号解调策略，设计了基于微处理器的转子位置测量电路。所提方法以方波为激励信号，利用输出信号与转子位置正余弦存在的比例关系，通过激励信号与输出信号相乘实现解调。(A method based on square wave excitation and a new signal demodulation strategy are proposed. Meanwhile, the whole circuit based on MCU is designed for rotor position measurement. The proposed method takes square wave as the excitation signal, and uses the proportional relationship between the output signal and the sine and cosine of the rotor position to realize the demodulation, which can be completed by multiplying the excitation signal and the output signal.)
