A Robust Design, Method for a Long Dead-time System with an Integral Mode
ABSTRACT In this paper, we present a robust controller design method that can not only deal with a constant time delay plant but a1so the uncertain time delay one. For a constant time delay plant, the proposed DTC can independently adjust the set point response and the disturbance rejection response without any stability constraint. And in the uncertain time delay case, one can process the control design step with uncertainty norm bound. To verify real effectiveness, theoretical analysis and simulation results are given.
