MathWorks does not warrant, and disclaims all liability for, the accuracy, suitability, or fitness for purpose of the translation. The error is then abs(1-dcgain(sys)) This uses the fact that, for a stable linear system with transfer function H(s), steady-state value of step response = limit of H(s) as s->0 = Opportunities for recent engineering grads. Note: Steady-state error analysis is only useful for stable systems.

Let's first examine the ramp input response for a gain of K = 1. Related Content Join the 15-year community celebration. Learn MATLAB today! stepinfo then returns a NY-by-NU structure array S of performance metrics for each I/O pair.S = stepinfo(y,t) uses the last sample value of y as steady-state value yfinal.

Note: Steady-state error analysis is only useful for stable systems. The response has settled when the error |y(t) - yfinal| becomes smaller than a fraction ST of its peak value.

That is, the system type is equal to the value of n when the system is represented as in the following figure. Velocity Error Constant We choose to zoom in between 40 and 41 because we will be sure that the system has reached steady state by then and we will also be able to get when the response has reached the steady state).

Manipulating the blocks, we can transform the system into an equivalent unity-feedback structure as shown below. Here is my code: Code (Text): sys1 = 3 + tf(0.5.*[1], [1 0]); sys2 = tf([1], [1 3 8]); sys = feedback(sys1*sys2, 1) subplot(1,2,1) step(sys) hold on step(tf(1)) hold off sys3 That is, the system type is equal to the value of n when the system is represented as in the following figure: Therefore, a system can be type 0, type 1, The steady-state error will depend on the type of input (step, ramp, etc) as well as the system type (0, I, or II).
