Error Signal

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 error signal homeostasis communication system. Whatever the variable, it is important to control the variable accurately. If you error signal definition 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 reference signal particular value, you will 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 error signal 15 is sent to script how accurately you can control the 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 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 cont

(electricity) error voltage (electronics) A voltage that depends on the signal received from the target in http://encyclopedia2.thefreedictionary.com/error+signal a tracking system, having a polarity and magnitude dependent on the angle between the target and the center of the scanning beam. error signalA voltage whose magnitude is proportional to the difference between an actual and a desired position. In radar use, error signals are obtained from selsyns and automatic gain control circuits. The error signals are used to control servo systems, so that the resultant motions tend to correct the error. Want to thank TFD for its existence?
