非线性多变量零阶接近有界系统的多模型自适应控制
Multiple Model Adaptive Control for a Class of Nonlinear Multi-variable Systems with Zero-order Proximity Boundedness
摘要
Abstract
A novel multiple model adaptive control method us-ing neural networks is proposed for a class of MIMO nonlinear discrete-time systems. In order to relax the restriction of the higher order nonlinear term of the nonlinear system to zero-order proximity boundedness, this method introduces a new nonlinear model. The model adds a nonlinear compensation term to the conventional linear autoregressive model such that the estimation error is bounded. A neural network model is used to identify the system with nonlinear model simultane-ously. A performance-based switching mechanism determines the controller which has the better performance to control the system. Theoretic analysis proves the bounded-input-bounded-output stability of the zero-order proximity boundedness multi-ple model adaptive control system. Simulation results are pre-sented to show the effectiveness of the proposed method.关键词
