摘要
本文首先介绍了非线性系统能观性的各种定义,探讨了这些定义的背景,叙述了在各种定义下的研究成果,指出了尚未解决的问题,并介绍了Morse-Smale系统的能观性。其次,叙述了非线性系统设计状态观测器的五种方法,详细介绍了各种方法的假设条件和设计步骤。
This paper presents a survey of observability and observers of nonlinear systems. The background .conclusion and unsolved problems for the different definitions of observability are described. The conclusions regarding the observability of Morse-smale systems are also introduced. Five methods of designing observers for nonlinear systems,including assumptions, algorithms and demerits are discussed,respectively.
