ON OBSERVABILITY OF 3D CONTINUOUS-TIME AUTONOMOUS CHAOTIC SYSTEMS BASED ON SCALAR OUTPUT MEASUREMENT
- XIAO-SONG YANG
International Journal of Bifurcation and Chaos01 May 2002
Preview Abstract
In this paper, by means of case studies we discuss an observable feature of 3D continuous-time autonomous chaotic systems through scalar output and its time derivatives. We observe that the Lorenz system, the Rössler system, the Chua circuit and the Chen system are all observable based on scalar output and its derivatives. This leads to our conjecture that chaotic motion described by 3D continuous-time autonomous dynamical system is observable based on a scalar output and its first- and second-order derivatives. Finally, we present some mathematical analysis and put up some theoretical questions for future studies.
