How can I use a duty cycle result from a MATLAB fnc to control the duty cycle of a PWM generator, using Simulink.

I got it working... it was a scale problem. Instead of duty cycle = 0 to 1, my MATLAB fnc was outputtng duty cycle = 0 to 100.
After fixing my problem, I simply connected the MATLAN fnc to the input of the PWM generator and success.

can you do this in simscape also?with Controlled PWM Voltage ?

Hi can you tell me how to control the duty cycle of PWM using the output from PID Controller in Simulink.

Hello Stephen,
Can you please guide me as to how you can control a Duty Ratio of PWM in Simulink by using the stored values of Duty Ratio from MATLAB.
Looks like you have already done this so please help ? Any inputs would be helpful.

Hi Stephen,
I wish to generate pwm signal and send it to the microcontroller through the serial communication. Can you aid me on how you generated the pwm signal? Thanks. Your help is much appreciate.

Serial communications protocols use fixed bit-widths, and so are not able to convey the variable pulse widths needed for Pulse Width Modification. Not unless what you send is a _description_ of the pulses.
