时滞不确定飞行系统神经网络非脆弱H∞控制
Neural network non-fragile H∞ control for time delay uncertain flight system,
摘要
Abstract
The neural network non-fragile H8 control scheme is presented for time-varying uncertain flight systems with parameter perturbation and state time delay.This flight control scheme combines the robust H8 controller with neural network controller. The Radial Basis Function Neural Network (RBFNN) is adopted to approximate the nonlinear uncertain term of the flight system.The robust controller is designed using Linear Matrix Inequality(LMI) for the nominal linear flight system.And then, the uncertain nonlinear input term is compensated using the neural network.The stability analysis has been given for considering the effects of the parameter perturbation, the time delay and the neural network weight via the Lyapunov analysis.The closed-loop system stability has been proved under the proposed flight control scheme. Simulation results illustrate that the flight control scheme is effective.关键词
