It is denoted by ess and its Laplace transformation is denoted by E(s). When the reference input is applied to the given system then the information given about the level of desired output is observed. The actual output is feed back to the input side and it is compared with the input signal. Thus steady state error can also be defined as the difference between the reference input and the feedback signal. This post includes Control system notes on Steady State Error explaining Effect of Input on Steady state error, Static error coefficient and derivation of Steady state error in detail. Derivation of Steady state error: Consider a simple closed loop system as shown in figure below: Closed Loop System Different notation used R(s)= L

Dynamic error coefficient 1.) Static error coefficient:- the ability of the system to reduce or eliminate the steady state error is static error coefficient they are of 3 different types. 1.) position error coefficient:- related to the output of the system. it is denoted by kp. 2.) velocity error coefficient:- related to the rate of change of output of the system. it is denoted by kv. 3.)acceleration error coefficient:- related to the rate of change of output. it denoted by ka.

Error Click here to return to the Table of Contents Why Worry About Steady State Error? Control systems are used to control some physical variable. That variable may be a temperature somewhere, the attitude of an aircraft or a frequency in a communication system. Whatever https://www.facstaff.bucknell.edu/mastascu/eControlHTML/Design/Perf1SSE.htm the variable, it is important to control the variable accurately. If you are designing a control system, how accurately the system performs is important. If it is desired to have the variable under control take on a particular value, you will https://www.scribd.com/doc/118662280/Basic-Control-System-Engineering want the variable to get as close to the desired value as possible. Certainly, you will want to measure how accurately you can control the variable. Beyond that you will want to be able to predict how accurately you can control the standard error variable. To be able to measure and predict accuracy in a control system, a standard measure of performance is widely used. That measure of performance is steady state error - SSE - and steady state error is a concept that assumes the following: The system under test is stimulated with some standard input. Typically, the test input is a step function of time, but it can also be a ramp or other polynomial kinds of inputs. The system comes to a steady state, and standard error of the difference between the input and the output is measured. The difference between the input - the desired response - and the output - the actual response is referred to as the error. Goals For This Lesson Given our statements above, it should be clear what you are about in this lesson. Here are your goals. Given a linear feedback control system, Be able to compute the SSE for standard inputs, particularly step input signals. Be able to compute the gain that will produce a prescribed level of SSE in the system. Be able to specify the SSE in a system with integral control. In this lesson, we will examine steady state error - SSE - in closed loop control systems. The closed loop system we will examine is shown below. The system to be controlled has a transfer function G(s). There is a sensor with a transfer function Ks. There is a controller with a transfer function Kp(s) - which may be a constant gain. What Is SSE? We need a precise definition of SSE if we are going to be able to predict a value for SSE in a closed loop control system. Next, we'll look at a closed loop system and determine precisely what is meant by SSE. In this lesson, we will examine steady state error - SSE - in closed loop control systems. The closed loop system we will examine is shown below. The system to be controlled has a
