本文研究了线性多变量系统直接模型参考自适应控制(DMRAC)问题。本文提出了一种带有“加速因子”的自适应控制算法,并利用 Lyapunov 函数分析了其稳定性。该算法可以保证受控对象输出跟随参考模型输出而无需进行参数辩别与状态滤波,也不要求系统满足完全模型跟随条件,因而在实现上十分方便。运用此法对用于某型飞机的自适应飞机控制系统进行设计,获得满意效果。 This paper studies the direct model reference adaptive control (DMRAC) problem of linear multivariable systems. In this paper, an adaptive control algorithm with “acceleration factor” is proposed and its stability is analyzed by Lyapunov function. The algorithm can guarantee that the output of the controlled object follows the output of the reference model without parameter discrimination and state filtering and does not require the system to satisfy the complete model following condition, so it is very convenient to realize. This method is used to design an adaptive aircraft control system for a certain type of aircraft and obtain satisfactory results.
