response has reached steady state). The steady-state error will depend on the type of input (step, ramp, etc.) as well as the system type (0, I,

or II). Note: Steady-state error analysis is only useful for stable systems. You should always check the system for stability before performing a steady-state error analysis. Many of the techniques that we present will give an answer even if the error does not reach a finite steady-state value. Calculating steady-state errors Before talking how to reduce steady state error about the relationships between steady-state error and system type, we will show how to calculate error regardless of system type or input. Then, we will start deriving formulas we can apply when the system has a specific structure and the input is one of our standard functions. Steady-state error can be calculated from the open- or closed-loop transfer function for unity feedback systems. For example, let's say that we have the system given below. This is equivalent to the following system, where T(s) is the closed-loop transfer function. We can calculate the steady-state error for this system from either the open- or closed-loop transfer function using the Final Value Theorem. Recall that this theorem can only be applied if the subject of the limit (sE(s) in this case) has poles with negative real part. (1) (2) Now, let's plug in the Laplace transforms for some standard inputs and determine equations to calculate steady-state error fro

So I already know how to find steady-state by going to the graph and right click on graph and then go to characteristics. However, I trying to calculate the steady-state error without using characteristic feature. I don't know if I done correctly.

R(s) can be interpreted as the desired value of the output, and the output of the summing junction, E(s), is the error between the desired and actual output values. The behavior of this error signal as time t goes to infinity (the steady-state error) is the topic of this example. The Final Value Theorem of Laplace Transforms will be used to determine the steady-state error. The one very important requirement for using the Final Value Theorem correctly in this type of application is that the closed-loop system must be BIBO stable, that is, all poles of the closed-loop transfer function C(s)/R(s) must be strictly in the left-half of the s-plane. Steady-state error in terms of System Type and Input Type Input Signals -- The steady-state error will be determined for a particular class of reference input signals, namely those signals that can be expressed in the time domain as simple powers of t, such as step, ramp, parabola, etc. The Laplace Transforms for signals in this class all have the form System Type -- With this type of input signal, the steady-state error ess will depend on the open-loop transfer function Gp(s) in a very simple way. We will define the System Type to be the number of poles of Gp(s) at the origin of the s-plane (s=0), and denote the System Type by N. The relation between the System Type N and the Type of the reference input signal q determines the form of the steady-state error. We will see that the steady-state error can only have 3 possible forms: zero a non-zero, finite number infinity As seen in the equations below, the form of the steady-state error only depends on the value of N+1-q. If that value is positive, the numerator of ess evaluates to 0 when the limit is taken, and thus the steady-state error is zero. If N+1-q is
