I want to simulate exercising machine with motor simulating weights by limiting it's torque. Changing torque limit would be equal to changing mass of weights on exercising machine.
I already have anti-windup PI controller in my code. Gain (Kc) of anti-windup part of controller is equal to integral gain.
Do I have to limit exits of both speed and q-current controllers or just one of them?
Just came across my mind, can I give a reference for D-current, instead of directly trying to limit Q-current? It will decrease overral flux in motor and, consequently, decrease electromagnetic torque generated by motor.
Would it be safe for motor, because D component of stator current is...
Motor is 1.23 kW, 400 V. I didn't connect braking resistor on my board yet, but I figured it isn't neccesary because of small value of motor power. There is small amount of energy generated by motor while I'm spinning it with my hand to check torque.
I didn't implement any braking functions in...
I'm not sure I've understood you well. How do you mean 'use a steady DC current across the fields'? Can it be done by changing my code or are there harware changes?
And could you please tell why can't it be done simply by limiting outputs of speed and/or Q-current PI controllers?
Hi,
I'm controlling my PMSM at zero speed. While I'm trying to move its shaft I don't want my motor to generate its maximum torque to resist my movement but the limited one.
Everything went fine with classic control, but as soon as I tried to limit it's torque -- by limiting outputs of speed...
