量化网络控制系统的能控性与能观性

将网络引入控制系统不可避免地引起很多新的问题,传统意义下的系统能控性与能观性在应用到网络化系统时必须重新考虑.针对网络控制系统中普遍存在的信息量化问题,研究网络控制系统的基本问题.定义量化网络控制系统的能控性与能观性,给出系统能控和能观的充分条件,指出量化网络控制系统的能控性与能观性取决于量化阶距的选取.

Controllability and observability of quantitative networked control systems

The introduction of the communication network into a control system brings inevitably many new problems.Controllability and observability in traditional sense must be reconsidered before they can be applied to networked systems.In this paper,fundamental problems of networked control systems were investigated in view of the quantization effect which exists generally in networked setting.New concepts,called as controllability and observability of NCS with quantization,were defined and sufficient conditions for system to be controllable and observable were put forward.It was pointed out that such controllability and observability were dependent on the selection of the quantization sensitivity.
