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 about the relationships between steady-state error and system type, we will show how to calculate determine the steady state error for a unit step input 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 from the open-loop transfer function in each case. Step Input (R(s) = 1 / s): (3) Ramp Input (R(s) = 1 / s^2): (4) Parabolic Input (R(s) = 1 / s^3): (

Did you mean steady-state value, not "steady-error value"? Assuming that's what you meant, the next clarification is steady-state value of a transfer function in response to what - is it in response to a step input?If that's what you meant, then yes, you can do this like that:>> s=tf('s'); >> sys=5/(s^2+2*s+25); >> [y,t]=step(sys); >> y(length(y)
