本文对文献[2]提出的自适应观测器的设计及其在自适应控制系统中的应用几个问题进行了讨论。提出了在对象特性部分已知且不变的情况下简化自适应观测器的设计的方法。提出了一种采用闭环控制消除参数估算偏差的方法。讨论了应用这种自适应观测器去任意设置控制系统的零极点的方法,并提出了在对象特性有一部分已知且不变时简化控制系统的方案。
In this paper, the design of adaptive observer proposed in [2] and its application in adaptive control system are discussed. A method of simplifying the design of the adaptive observer is proposed in the case where the characteristics of the object are known and unchanged. A method of using closed-loop control to eliminate parameter estimation bias is proposed. The method of using this kind of adaptive observer to arbitrarily set the zero pole of the control system is discussed. The scheme of simplifying the control system when the object characteristic is partly known and unchanged is proposed.
