Steady State Error
When the output of the system is deviated from the desired response during steady state, this deviation is known as steady state error. We use final value theorem for calculating the steady state error.
or,
Any system is called controlled system if output follows input at steady state or steady state error is as low as possible.
When we have input as unit step signal the error is known as position error and
When we have input as unit ramp the error is known as velocity error and
When we have input as unit parabolic the error is acceleration error and

Steady State Response
In this article, we are going to discuss the steady-state response. We will see what is steady state response in Time domain analysis. We will then discuss some of the standard test signals used in finding the response of a response. We also discuss the first-order response for different signals. We will discuss the second-order system and its cases. Along with these, we will also discuss some specifications and errors. Later in the article, we will discuss some applications, advantages, and disadvantages of steady-state response.
