Robust output feedback control design of decentralized stochastic singularly-perturbed computer controlled systems with multiple time-varying delays

The control algorithm of an output feedback control scheme for robust optimal stabilizing control of a decentralized stochastic singularly-perturbed computer controlled system with multiple time-varying delays is designed. The technique is based on singular perturbation methodology, computer control theory, stochastic control theory, and the time separation principle. The output feedback controller is designed to control the dominant poles in an approximated reduced-order system model for robust optimal control performances. Applying the proposed time separation principle concerned with each delay moment, the problem of multiple time-varying delays is also solved.
