Question: Which controller is used to eliminate steady-state error in a system?

Options:

Correct Answer: Integral controller

Solution:

An integral controller is specifically designed to eliminate steady-state error by integrating the error over time.

Which controller is used to eliminate steady-state error in a system?

Step 1: Understand what steady-state error is. It is the difference between the desired output and the actual output of a system when it has settled down.
Step 2: Learn about controllers in control systems. Controllers help manage the output of a system based on the input and the error.
Step 3: Identify the types of controllers. Common types include proportional, integral, and derivative controllers.
Step 4: Focus on the integral controller. This type of controller adds up the error over time.
Step 5: Realize that by integrating the error, the integral controller can adjust the system's output to eliminate the steady-state error.
Step 6: Conclude that the integral controller is the one specifically used to eliminate steady-state error.
