Explore the concept of negative feedback and its role in maintaining system stability across various applications.

While the basic implementation looks simple for a series PID, the positive feedback path can have you going in circles. Also, I have not seen any block diagram that shows how feedforward signals and ...

In a typical PID controller these elements are driven by a combination of the system command and the feedback signal from the object that is being controlled (usually referred to as the “plant”).

For this unit, the PID controller board needs to output a 12-V PWM signal to control motor speed, and use an analog-to-digital converter (ADC) channel to sense the position of the actuator.
