Correlation between the output of PID operation and the actuator PWM duty cycle [Copy link]

How to convert the PID calculation result to the PWM duty cycle? For example, when using PWM to control temperature or speed, the PID calculation function result PID_Calc(); obtained by the PID formula, and the PWM output duty cycle function PWM(Duty);, where the parameter of the duty cycle function is the duty cycle Duty, how to convert the PID output result to the duty cycle Duty? Is it to directly assign the PID output result to Duty?

PID is a value that your regulator will output after adjustment. You need to process this value so that the value fluctuates within the adjustable range of your duty cycle, and then assign the PID-adjusted value to the PWM wave port.

You need to do experiments to determine it. These parameters are related to your system response time and software control cycle, so you have to do it yourself.
