The steam superheater and the steam pressure systems are time delay systems that have poles near the origin in the left half plane or a pure integrator. Smith predictor can't be applied to these systems any more, because of the steady state error for the step disturbance. In this paper, a new Smith predictor controller is proposed for the steam superheater and the steam pressure. A disturbance observer to estimate an input disturbance and a new controller to eliminate an effect of a disturbance… CONTINUE READING
