针对慢变化未知系数的单输入——单输出线性模型被控对象,本文提出了一种设计离散模型参考自适应控制系统的新方法。该方法通过恰当地选择自适应控制律,从而将系统转化为满足 Popov 超稳定条件的非线性时变反馈系统。飞行器控制方面的一个实例表明该方法具有实现容易、跟踪速度快等特点。
Aiming at the single-input-single-output linear model controlled by slowly varying unknown coefficients, a new method for designing discrete-model reference adaptive control system is proposed in this paper. This method transforms the system into a nonlinear time-varying feedback system that satisfies Popov’s supper-stable condition by properly choosing the adaptive control law. An example of aircraft control shows that this method has the characteristics of easy implementation and fast tracking.
