Internal Model Control considering saturation mismatch

This paper is concerned with internal model control for time delay systems with input saturation. The scheme is applied to temperature control system. Nonlinearity is a fatal role in control system. Input saturation with integral operation causes overshoot response, which is called "Windup". The input time delay has a potential to make an overshoot increase. Several strategies against "Windup" were developed especially in PID controller, however, almost strategies did not consider the time delay effect. In this paper, a strategy for internal model control against saturation and its mismatch is proposed. Copyright (C) 1998 IFAC.
