关于控制系统的局部线性化

On local linearization of control systems

Laurent Baratchart, Jean-Baptiste Pomet

摘要:

我们考虑光滑(C无穷大或实解析)控制系统的拓扑线性化问题,即通过对状态和控制(静态反馈变换)进行拓扑但不一定可微的逐点变换,使其局部等价于线性可控系统。我们证明了局部拓扑线性化蕴涵局部光滑线性化,在泛点。在任意点上,它意味着通过一个同胚局部共轭到一个线性系,这个同胚在状态变量上引起一个光滑的同胚,并且,除了在“强”奇点,这个同胚可以被选择为一个光滑映射(逆映射不需要是光滑的)。确定在“强”奇点上是否也是如此,就等于解决了微分拓扑中一个有趣的公开问题。

英文摘要:

We consider the problem of topological linearization of smooth (C infinity or real analytic) control systems, i.e. of their local equivalence to a linear controllable system via point-wise transformations on the state and the control (static feedback transformations) that are topological but not necessarily differentiable. We prove that local topological linearization implies local smooth linearization, at generic points. At arbitrary points, it implies local conjugation to a linear system via a homeomorphism that induces a smooth diffeomorphism on the state variables, and, except at "strongly" singular points, this homeomorphism can be chosen to be a smooth mapping (the inverse map needs not be smooth). Deciding whether the same is true at "strongly" singular points is tantamount to solve an intriguing open question in differential topology.
