Compensators in Control Systems
In a control system, what is a compensator?
A compensator is a part or a group of parts that are added to a control system in order to alter its behavior, usually with the purpose of enhancing its robustness, performance, or stability.
Why would someone use a compensator?
A compensator’s main objective is to modify the response of the closed-loop system in order to satisfy performance requirements that include stability margins, steady-state error, and transient response.
Which kinds of compensators are there?
Proportional-integral-derivative (PID) controllers, lead compensators, lag compensators, lead-lag compensators, and state-feedback controllers are examples of common compensator types.
What factors should be taken into account when choosing a compensator?
Stability requirements, performance criteria, robustness to uncertainties and disturbances, complexity, implementation restrictions, and cost-effectiveness are all important factors to take into account.

All of the topics covered in the Control System Tutorial, including the Introduction to Control Systems, Classification, Transfer Function, Signal Flow Graphs, Mason Gain Formula, Block Diagram, State Space Model, and more, are included in our tutorial.
The compensator is an extra part that is introduced to the control system’s structure throughout its redesign. It is included in order to make up for the system’s poor performance. A compensator can be mechanical, electrical, hydraulic, or any combination of these.
