Optimal Disturbance Attenuation for Networked Control Systems with Long Time-Delay
Based on the fuzzy fusion technology, this paper studies a modeling approach for networked control systems with network-induced time-delay which is longer than a sampling period. The system with long control time-delay is transformed into the one without time-delay. The Kalman filter is employed for the optimal state estimate of white-noise processes and the physically realizable problem of optimal disturbance attenuation control law is solved. Then the existence and uniqueness conditions of feedforward and feedback optimal control law are proposed, and the algorithm of solving the optimal control problem is presented. The simulation results show that the method is efficient and more robust than the classical state feedback optimal control with respect to errors produced by the external disturbances.
