Hey guys, currently i'm doing a project controlling a Servo motor with a PID feedback of a temperature sensor (4-20mA), the servo valve receives DO to open and close to actuates a 3 way valve.
By tapping into the feedback from the servo motor (0-10V) to the PID controller,
in this case PV will be the temperature.
but i'm a little bit confuse, By setting the PV from the temperature, where should i put the feedback form the motor??
I'm trying to build the concept for the PID control in a general way, it should be like this?
