As for the time constant T, two factors need to be considered. Firstly, the filter should have the ability to filter out the high frequency ripple of ΔVs to reduce the current oscillation. On the other hand, the dynamic torque response needs to be considered. That is, the transient curre...
According to the analysis in Section 3.5, using a low-pass filter and designing a smooth switching strategy can solve this problem better; the weights are dynamically adjusted according to the working conditions when the motor is running, taking into account both dynamic and steady-state ...
