Abstract

In this paper, observer-based output feedback control is developed for discrete-time systems with multiple state delays and input delays. In order to estimate the system state, two types of state observers are designed, including a full-order observer and a reduced-order state observer. With the estimated state generated by the designed observers, predictor-based control laws are implemented. Further, the separation property of the closed-loop system under the designed control laws is revealed.
