To disable the ePWM block in real-time, you can try using an enable subsystem or control the execution of the pwm block using a condition in your code. For example, you can use a MATLAB function that sets the ePWM block enable signal based on your desired conditions.
Here are the general steps to create an enable subsystem:
1. Right-click on the ePWM block and select "Create > Subsystem > Enable Subsystem" from the menu.
2. Connect the enable signal to the Enable port of the newly created subsystem.
3. Inside the subsystem, connect the ePWM block to the main output signal path.
4. Write a MATLAB function that sets the enable signal based on your desired conditions.
5. Pass the enable signal to the subsystem input port in your model and use the MATLAB function to control its value.
By using this approach, the ePWM block will not process its output when it is disabled and its output will be both zero.
