This paper considers truncated predictor feedback (TPF) stabilization of periodic linear systems with time-varying input delays with its applications to the elliptical spacecraft rendezvous. By carefully investigating the solutions and properties to a class of parametric Lyapunov differential equations, it is proved that TPF controllers can stabilize the periodic linear time-delay systems with arbitrarily...
In the fields of chaos detection, it has become an important problem to confirm the bifurcation threshold value of the chaos detection system. It is directly related to the detection precision of the chaos system. In this paper, on the analysis of the relationship between bifurcation process and structure stability of the system, the Floquet exponents in periodic state is employed to determine the...
This paper proposes a matching template based on first order differential coefficient for fast edge extracting after analyzing and synthesizing the traditional algorithm of edge detection. The method is able to effectively thinning the image edge and increase the accuracy and efficiency.
