英文摘要

      ln this paper，a decentralized self-tuning control algorithm using polynomial approximation is presented for linear time-varying discrete large-scale systems consiting of subsystems with bounded distur-bances and nonlinear interconnections. We also propose using neural networks to realize the decentralized self-tuning control. The neural networks are employed to predict the plant model and use as a controller. The Widrow-Hoff rule is used as learning algorithm for. the networks. The simulation results demonstrate that the system is stable and can track the desired output quite well.
