The motor is NOT seeing a 4,000 Hz square wave current. The motor is an
inductive load and it is filtering the 4KHz to nearly DC. Look and see,
Use a real scope (no hal scope) on the line and look at current v. time.
Look at the PID controller. it will always oscillate if you are trying to

The trick is to null the error without changing the sign of the error.
If the sign changes, then it

Isn't that what the deadband parameter into the PID does?

This is an HTML corruption ,
