Hey,
When running a motor through inverter (both parameterized thus non-ideal), the starting speed in RPM reaches approximately 1500 RPM in 0.02sec and and oscilates, it should increase gradually. Moreover, I have given a load torque signal, but liek speed torque is oscillating instead of become stable even after few seconds.
What could be the issue here. The speed and torque snapshots are attached here.

Hi: It all depends upon the model configuration such as whether the model is open loop or closed loop and whether any speed or torque controllers are used in the model etc.

its open loop, no controller is used yet. The switching is done through simple SPWM applied to the inverter.

Hi: I can't predict anything unless I am able to see the model.
