Title: A NOVEL APPROACH TO ADAPTIVE CONTROL OF NETWORKED SYSTEMS
Authors: Mr. A. H. Tahoun, Dr. Fang Hua- Jing
Abstract:
The insertion of communication network in the feedback adaptive control loops makes the analysis and design of networked control systems more and more complex. This paper addresses the stability problem of linear time-invariant adaptive networked control systems. Our approach is novel in that the knowledge of the exact values of all system parameters is not required. The case of state feedback is treated in which an upper bound on the norm of matrix A is required to be known. The priori knowledge of upper bound on norm A is not required in constructing the controller but it is required only to determine an upper bound on the transmission period h that guarantees the stability of the overall adaptive networked control system under an ideal transmission process, i.e. no transmission delay or packet dropout Rigorous mathematical proofs are established relies heavily on Lyapunov's stability criterion. Simulation results are given to illustrate the efficacy of our design approach.
