Investigation of Time-Varying Model Reference Adaptive Control for a Kind of Missile

本文旨在研究用参考模型自适应控制理论设计一种导弹控制器 ,重点介绍了时变参考模型设计过程。参考模型由根据经典控制理论确定的定常参数跟随模型和反馈环节组成 ,并用最优理论完成时变参考模型的设计 ,使得对象在最短的时间内达到所给定的状态。给出采用时变模型参考自适应控制的制导系统的数字仿真结果。

A major motivation for this paper is to investigation designing of a controller on the basis of the theory of model reference adaptive control for a kind of missile, and lay emphasis on design process of a time varying reference model. Composed of a following model which was constant in time and was determined depend on classical control theory and a feedback unit, the time varying reference model designed was accomplished by virtue of optimization theory. It can be make the object achieve a given state in the shortest time. Digital simulation results of the guidance system adopting adaptive control with time varying reference model were presented in the paper.
