hello, In a DC-DC boost converter during double-loop control process, CMC (Current mode control) why does the voltage control work better than VMC (voltage mode control) when load changes when the current is introduced as the inner loop feedback ?
Given enough effort, both VMC and CMC will be very high performance. However, generally CMC is "easier" to make high performance...

Why the output from Alpha Beta to D,Q block is not in DC???
If you are not getting a steady output on the DQ side this means that the angle input to the transformation is wrong. If you dou...

How to specify rotor inertia in asynchronous machine if speed is selected as mechanical input?
If speed is your input variable, then you are defining what the speed will be. Thus, modeling the inertia and friction internall...

The speed of the induction motor in matlab simulink is not starting from zero. It is starting from a higher value of around 1400 rpm. What is the reason behind this ?
Hi Suruchi, your initial condition for slip must be set to 1 for the speed to start at zero, like shown in the image below. ...
