Abstract EN
Voltage model is commonly used in direct torque control (DTC) for flux observing of asynchronous motor.
In order to improve low-speed and dynamic performance of the voltage model, a modified low-pass filter (LPF) algorithm is proposed.
Firstly, the tracking differentiator is brought in to modulate the measured stator current, which suppresses the measurement noise, and then amplitude and phase compensation is made towards the stator electromotive force (EMF), after which the stator flux is obtained through a low-pass filter.
This method can eliminate the dynamic error of flux filtered by LPF and improve low-speed performance.
Experimental results demonstrate effectiveness and improved dynamic performance of such method.
