    Abstract: A permanent magnet synchronous motor is controlled using d-axis current and q-axis current along with respective d-current and q-current feedback loops. The speed and position of the motor are determined by injecting a first signal into the d-axis current and observing the response in the q-current feedback loop. Part of the q-current feedback signal is demodulated with a second signal which is 90 degrees out of phase from the first signal. The demodulated signal is preferably sent through a low pass filter before being received by an observer controller. The observer controller outputs a position estimate which is used to modify the d-current feedback signal and a speed estimate which is used to modify the q-axis current.

    Abstract translation: 使用d轴电流和q轴电流以及相应的d电流和q电流反馈回路来控制永磁同步电动机。 通过将第一信号注入d轴电流并观察q电流反馈回路中的响应来确定电动机的速度和位置。 q电流反馈信号的一部分用与第一信号相差90度的第二信号进行解调。 解调信号优选地在被观察者控制器接收之前通过低通滤波器发送。 观察者控制器输出用于修改d电流反馈信号的位置估计和用于修改q轴电流的速度估计。
