Hello Everyone,
I have been trying to follow the example model "PMSM Velocity Control" where my final objective is to replace the idela converter with parameterized discrete devices. For now, I am using ideal converter, with different reference speed (Drive Cycle, constant, signal editor) and I have tuned the speed and current loops accordingly.
The Sample Time
Control Sample time (TSc) = Tsw/250 (Switching time over 250 samples per switching time)
PWM Sample time (TS) = 1/(10*fsw)
The motor is seem to follow the reference speed correctly, however the generated agte signals are seem to sampled sine wave, between 1 and -1.
The voltage (Phase-phase) and (Phase-to-Nuetral) waveform is quite unusual (my input is 48V)
Although the control loops are tuned and there is very low oscillation in the controlled output, however the phase current has hige distortion which I tried to suppress via low-pass filter.
When I put the parameterized semicondcutor instead of idela converter, the gate are signal are not even generating. A gate driver is used to provide PWM signal form the controller to the N-channel MOSFET.
I am attaching few screenshots and my model, if any could validate the model and provide the guidance regarding aforementioned.
