【摘要】 将文献[1,2]的研究结果推广到具有未知控制方向和模型参数的高阶线性离散时间系统,研究一般线性系统的间接自适应调节．采用3种不同的估计器分别结合修改的确定性等价控制律,克服了当系统增益的估计值为零时可能丧失稳定性(或能控性)的困难,对所设计的闭环系统的稳定性进行了分析,并给出该系统全局稳定的结论．两个仿真验证了所设计的自适应调节系统的有界性．更多还原

【Abstract】 It investigates indirect adaptive regulators for the general linear systems and extends the results of Ruan et al. [1,2] to the general case of the higher order linear discrete-time systems with the unknown control directions and model parameters. Three different estimators and the modified certainty-equivalence control law are maduse of. the difficulty of a loss of stability (or controllability) as the estimate of the plant gain is zero is overcome and analyze the stability of the designed closed-loop system is analyzed. This analysis provides a conclusion of the global stability of the systems. Two simulation examples show that the resulting adaptive regulating systems are of the boundedness properties.更多还原
