Pid Controller Approximating Gmvc with Pole-placement Using Steady-state Predictive Output

This paper proposes a new design method of a PID controller. We design the PID controller based on generalized minimum variance control (GMVC) with a steady state predictive output (GMVCS). The proposed method has better approximation than conventional design schemes since the orders of compensators of a GMVCS law do not increase even if a dead-time increases. Furthermore, in this paper it is shown that GMVCS has an advantage that it is possible to place poles of the closed-loop system at desired places. Hence, the PID controller is designed based on the pole-placement GMVCS. Finally, we illustrate numerical simulation results in order to show the effectiveness of the proposed control algorithm.
