What is the difference between regulatory control system and servo system?

Answer 1

Well, sweetheart, a regulatory control system is like a strict parent that keeps things in line by maintaining a set value, while a servo system is more like a personal assistant that adjusts based on feedback to reach a desired position or speed. So basically, one plays by the rules, while the other is more flexible and adaptive. Hope that clears things up for you, pumpkin!

Answer 2

A servo control loop is one which responds to a change in setpoint. The setpoint may be changed as a function of time (typical of this are batch processes), and therefore the controlled variable must follow the setpoint.

and,

A regulatory control loop is one which responds to a change in some input value, bringing the system back to steady state. Regulatory control is by far more common than servo control in the process industries.

Answer 3

When setpoint is changed and PV moves to SP, this is servo controls. When the disturnbances are rejected by the control system , then it is regulatory controls.
