Iterative design of state predictive LQG controller for inertia rotor with time delay

Abstract It is known that LQG controller can be composed by using the state predictor for the input time delay system. Iterative design that improves the control performance of the closed-loop system has been proposed by repeating LQG control and closed-loop identification. In this research, the theory is verified by experiment of the swing control for the inertia rotor with an artificial time delay.
