Hello, I was running the example for PWM Motor Drive as provided in the Matlab help page here https://se.mathworks.com/help/physmod/sps/powersys/ug/simulating-variable-speed-motor-control.html. I wanted to simulate it at discrete time, so I followed the instructions as per section "Discretizing the PWM Motor Drive". However, I get the error "The "FixedStepDiscrete" solver cannot be used to simulate block diagram 'motor_drive_matlabexample' because it contains continuous states".
Can someone tell me what I am doing wrong? I attach the Simulink file.
