Question: Which component of a PID controller is responsible for eliminating steady-state error?

Options:

Correct Answer: Integral

Solution:

The integral component of a PID controller accumulates the error over time, effectively eliminating steady-state error.

Which component of a PID controller is responsible for eliminating steady-state error?

Which component of a PID controller is responsible for eliminating steady-state error?

Step 1: Understand what a PID controller is. It is a control system that uses three components: Proportional, Integral, and Derivative.
Step 2: Identify the purpose of each component. The Proportional component responds to the current error, the Derivative component predicts future error, and the Integral component accumulates past errors.
Step 3: Focus on the Integral component. This part adds up all the past errors over time.
Step 4: Realize that by accumulating these past errors, the Integral component helps to correct any persistent error that does not go away, known as steady-state error.
Step 5: Conclude that the Integral component is responsible for eliminating steady-state error in a PID controller.
