Abstract

Abstract:

An on-line neural network.based adaptive controller is presented to solve the problem of weak adaptability of existing linear control systems.The network weights are regulated according to the error between the reference model and the plant.and the structural uncertainties and unknown disturbances are counteracted on line by the neural network.The proposed controller is then designed and simulated with the attitude control of a spacecraft as an example.The results indicate that the uncertainties are tracked and compensated on line by the neural network with high accuracy and the dynamic performan ce of the linear control system is considerably improved.

Key words: neural network, adaptive control, linear control, spacecraft attitude control
