What are the types of compensators in control systems?
In most of the time, it is done by conditioning the input or the output to that system. There are three types of compensators: lag, lead and lag-lead compensators. 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 are the different types of compensators in feedback control?
There are various types of compensators that achieve these objectives in a feedback control system. Two common types of compensators are lead and lag compensators. Both the compensators introduce a pole and a zero the system. The transfer function of the compensator takes the form of:
What is the difference between a compensator and a controller?
In other words, aim of controller design is to reduce the error between the reference and the output signal which is feedback to the controller with input (reference) signal. A compensator : modification of system dynamics, to improve characteristics of the open-loop plant so that it can safely be used with feedback control.
What is a compensator in Electrical Engineering?
The system can be either replaced by a new system or it can be provided with a unit called compensators. The compensators are used to improve the performance of the system during runtime. In this chapter, we shall discuss electric network realization of basic compensators and their frequency characteristics.
What are the types of compensating devices?
Compensating devices are may be in the form of electrical, mechanical, hydraulic etc. Most electrical compensator are RC filter. The simplest network used for compensator are known as lead, lag network.
