    How to connect a PI controller in a circuit

    Hi
    I want to use a PI controller to control a 3 Phase BLDC motor, to which power will be supplied using a dc battery.
    However I am confused since in my case, a battery always gives constant voltage, so how and what should the controller be connected to?

    I am using the demo model https://www.mathworks.com/help/physm...-inverter.html as reference.

    Right, PI controller is only applicable if the BLCD driver circuit has a voltage/current control feature, usually implemented as PWM.

    Re: How to connect a PI controller in a circuit

    Can you help me how to build a PWM circuit electronically for the 3 phase BLDC motor? On the internet I have found ways to build it using arduino, but I don't want to use an arduino. I haven't worked with it before.
