Optimal Disturbance Rejection for Discrete-time Systems with Time-Delay in Control Input
This paper considers the optimal disturbance rejection for discrete-time systems with time-delay in control input. First, by using a variable transformation, the system with time-delay in control input is transformed into a non-delayed system with disturbance, and the quadratic performance index of the optimal tracking control is transformed into a relevant format. The feedforward control law with a state feedback, a disturbance feedforward and a control memory term is derived from a Riccati equation and a Stein equation. A disturbance state observer is constructed to make the feedforward compensator physically realize. Simulation results demonstrate the effectiveness of the optimal rejection control law.This is the paper style requirement for the Chinese Control and Decision Conference.
