The remaining error constants and errors can be written by inspection, since we know that the system type is zero, or they can be calculated from their definitions: lim lim . 1 lim lim . When disturbance is 0, we have to use the superposition theorem to calculate the errors. The output signal is: 259 | p a g e: 1, 0. 5. To find yss and the resulting steady state error, apply the final value. Theorem in equation 1 2: y lim sy (s) lim y(t) lim s.
