非线性微分代数控制系统的反馈线性化

Feedback linearization of nonlinear differential-algebraic control systems

Yahao Chen

摘要:

本文研究非线性微分代数控制系统的反馈线性化问题。我们考虑两种反馈等价,即(局部)定义在整个广义状态空间上的外反馈等价和定义在局部最大受控不变子流形上的内反馈等价(即,在存在解决方案的集合上)。借助驱动变量显式化的概念,给出了DACS局部内反馈线性化和局部外反馈线性化的充要条件,该显式化概念将一类常微分方程控制系统(ODECSs)附加到给定的DACS上.我们发现,反馈线性化的DACS是密切相关的显式系统的线性化分布的对合性。最后,我们应用我们的结果反馈线性化的DAC系统的学术例子和约束机械系统。

英文摘要:

In this paper, we study feedback linearization problems for nonlinear differential-algebraic control systems (DACSs). We consider two kinds of feedback equivalences, namely, the external feedback equivalence, which is defined (locally) on the whole generalized state space, and the internal feedback equivalence, which is defined on the locally maximal controlled invariant submanifold (i.e., on the set where solutions exist). Necessary and sufficient conditions are given for the locally internal and the locally external feedback linearizability of DACSs with the help of a notion called the explicitation with driving variables, which attaches a class of ordinary differential equation control systems (ODECSs) to a given DACS. We show that the feedback linearizability of a DACS is closely related to the involutivity of the linearizability distributions of the explicitation systems. Finally, we apply our results of feedback linearization of DACSs to an academical example and a constrained mechanical system.
