Hi borboev,

I understand you need to simulate a tracking drive with a PWM controller. You can follow the below steps to perform this:

• Configure the “Controlled PWM Voltage” block for appropriate duty cycle, frequency, and amplitude to match the motor specifications.
• Set the “SCR” block parameters to control current flow effectively in synchronization with the PWM signal.
• Ensure that a feedback loop is implemented for precise control of the motor’s movement like using a PID controller to track the desired trajectory.

By adjusting these parameters, the simulation can accurately model the performance of a servo motor in a tracking drive controlled by PWM.
