What is compensating network in op amp?

Frequency compensation is implemented by modifying the gain and phase characteristics of the amplifier’s open loop output or of its feedback network, or both, in such a way as to avoid the conditions leading to oscillation. This is usually done by the internal or external use of resistance-capacitance networks.

What is compensator in control system?

A compensator is a component in the control system and it is used to regulate another system. In order to make the system behave as desired, it is necessary to redesign the system and add a compensator, a device which compensates for the deficient performance of the original system.

How does compensation circuit work?

The miller compensation circuit is shown below. In this technique, a capacitor is connected to the feedback with a resistor across the output. The circuit is a simple negative feedback amplifier with inverting gain dependent on R1 and R2. CF is the feedback capacitor which is used for the compensation purposes.

What is compensation technique?

It refers to the use of temperature sensitive devices such as diodes, transistors, thermistors which provide compensating voltage and current to maintain Q point stable. With increase of temperature ,R T decreases. Hence the voltage drop across it also decreases.

Why you will use compensating network?

Compensating networks are applied to the system in the form of feed forward path gain adjustment. Compensate a unstable system to make it stable. A compensating network is used to minimize overshoot. These compensating networks increase the steady state accuracy of the system.

What is meant by compensation in electronics?

In engineering, compensation is planning for side effects or other unintended issues in a design. Other examples in electrical engineering include: A constant voltage device compensates for low or high voltage in an electrical circuit, keeping its output the same within a given range of input.

What are the two types of compensation in control system?

There are three types of compensators — lag, lead and lag-lead compensators.

Which device is used in compensation technique?

Solution: Compensation techniques refer to the use of temperature sensitive devices such as thermistors, diodes, transistors, sensistors etc to compensate variation in currents.

What is the need of compensating network in control system?

Necessary of Compensation A compensating network is used to minimize overshoot. These compensating networks increase the steady state accuracy of the system. An important point to be noted here is that the increase in the steady state accuracy brings instability to the system.

What is the need of compensation in control system?

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.
