PID Controller Question & Answers

May 30, 2022 By WatElectronics

This article lists 75 PID Controller MCQs for Engineering Students. All the PID Controller Questions & Answers given below include solutions and links to the relevant topic. This is helpful for users who are preparing for their exams and interviews, or professionals who would like to brush up on the fundamentals of the PID controller.

The controllers are a very important component in a control system, which are usually used to control the steady-state error or transient response of the system. The proportional, proportional-integral, proportional integral derivative, and proportional derivate are the types of controllers. 

The P controller is a proportional controller, it is a device that produces an output that is proportional to the input signal. The proportional controller improves the steady-state error and also the stability of the system. It decreases the sensitivity of the system to parameter variations. The main disadvantage of a proportional controller is that it provides a constant steady-state error. 

The PI controller is a proportional-integral controller, it is a device that produces an output signal that consists of two terms one is proportional to the input system and the other one is proportional to the integral of the system. 

The PID controller is a proportional integral derivative system, this controller is very effective for slower processes. The response is faster in the PID controller compared to the PI controller. In PID controller some amount of overshoot may occur but in PI the overshoot doesn't occur.
