Hi everyone,
I am trying to implement the current control (Id, Iq) of a four pole PM synchronous motor. I am having trouble in making the Iq current follow a set reference.

I had also implemented a cascaded speed control for a dc motor.

In that case...
Hi everyone,
I have implemented PI control of speed of a PMDC motor under no load condition. I now intend to implement the same with a load added to it.
I want to compare the results with simulation as well. Is there any way of adding a known load to a DC motor. In my set up the dc motor is...
I am using PWM to control the motor current. First I calculate the duty cycle by the error between the reference and actual value.
This signal goes to the top switch. I invert the first PWM and give it to the lower switch.
The current sensor is in series with the motor and gives actual current...
Thanks a lot guys for the replies!
I did as you suggested and found the current in stand still condition to be around 180mA. I also adjusted the proportional and integral gain such that I have 100% duty cycle at this condition.
Now, when I give a reference less than 180mA and stop it, the dc...
Hi everybody!
I am trying to implement current control of a DC motor using a PI controller and was having a few questions.
I am supplying 19V as input voltage (and capable of supplying current upto 2A) to the H- bridge and the controlling is done via a microcontroller using PWM.
When I connect...
