I'm new to Simulink and I'm trying to get my hands a little dirty there to get used to using it. I'm working on a speed control of a switched reluctance motor. The input signal is to be fed to a converter (IGBT's gate) to control the speed of the motor.
Consider the general diagram below:
So my controller is a PID , my input is the reference speed of motor , my output is the measured (actual speed) of the motor and the plant is the "converter-motor" set up.
(1) What is the actuating signal obtained from the controller? Is it the control signal to be fed to the IGBTs?
(2) What if the plant input is a voltage (we are directly feeding voltage to the terminals of the motor). Isn't the PID output pretty much the same as the case of IGBTs? The Simulink controller produces a control signal how should I use it to feed voltage instead ?
