WebTo avoid having a steady state error, the proportional controller can be changed to u(t) = kpe(t)+ud, (10.4) where ud is a feedforward term that is adjusted to give the desired steady state value. If we choose ud = r/P(0) = krr, then the output will be exactly equal to the reference value, as it was in the state space case.

WebApr 10, 2024 · Steady state response is the behavior of a system after it has reached a stable condition in response to a constant input or disturbance. It is the response of a system when all the transient effects have died out, and the system has settled into a steady state. In other words, it is the behavior of the system over the long term, when the input ... WebEC2300 Control Systems Lab 4 – Steady -State Performance 2 Lab 4r4.doc, 5 April 2006
