Why Is Compensator Used?

A compensator is a component in the control system and it is used to regulate another system. ... Adjusting a control system in order to improve its performance might lead to unexpected behaviour (e.g. poor stability or even instability by increasing the gain value).

What is compensator and why it is required?

Compensator is used in the control system to improve system dynamics, improve characteristics of the open loop system, and improve stability. The lead/lag compensator, phase compensator is used to improve the stability of the system.

What is the difference between controller and compensator?

A compensator is a form of controller designed to alter certain characteristics (such as gain/phase) of the open-loop system. ... The difference between them is as follows: the compensator change the behavior of the open loop system while controller change the behavior of the close loop system.
