Output-feedback MRAC of networked control systems with network-induced delay

In this paper, an output-feedback model reference adaptive control scheme for networked control systems is developed. The key issues of networked control systems such as; channel bandwidth and delays induced by the insertion of data networks in the feedback adaptive control loops are considered. The advantage of this paper is the combination of different aspects in networked control systems; output-feedback model reference control of systems with unknown parameters, unknown sampling periods, and unknown network-induced delays. Error models, adaptive laws, and stability analysis are derived. Simulation results are given to illustrate the effectiveness of the proposed approach.
