摘要
本文对采用继电型自适应律的模型参考自适应控制系统提出了一种新的设计方法,并获得一种降阶自适应控制器。通过引入连续近似方法消除了不连续控制引起的颤抖现象。将本方法用于某飞行控制系统设计,其仿真结果表明效果良好。最后初步研究了本方法的微机实现问题。
This paper deals with the design problem of a model reference adaptive control system using relay-type adaptive law. A novel design method is presented and a reduced adaptive controller is obtained. The chattering phenomena caused by discontinuous control are eliminated with the technique of continuous approximation. Examples of the application of the method to the design of a flight control system are given. The results of simulation prove the effectiveness of the method. Finally, the problem of microcomputer implementation is briefly discussed.
