Based on the eigenvalue idea and the time-varying weighted vector norm in the state space R n we construct here the lower and upper bounds of the solutions of uniformly asymptotically stable linear systems. We generalize the known results for the linear time-invariant systems to the linear time-varying ones.

The stable linear switched systems will converge to the balance Point. If different switched laws be chosen, the convergence Process will not be the same, so there is an optimal switched law. The issues of optimal switched law based on norm, convergence radius, convergence distance and convergence direction are respectively studied, and the optimal switched law is confirmed by solution of matrix equation. All kinds of instance have been considered synthetically, the synthetic optimal switched law is given, by which an optimal status of system in convergence process is reflected roundly. By calculate and simulation of practice examples and the using process of stability criterion is realized distinctly.

Positivity of descriptor linear systems with regular pencilsThe positivity of descriptor continuous-time and discrete-time linear systems with regular pencils are addressed. Such systems can be reduced to standard linear systems and can be decomposed into dynamical and static parts. Two definitions of the positive systems are proposed. It is shown that the definitions are not equivalent. Conditions for the positivity of the systems and the relationship between two classes of positive systems are established. The considerations are illustrated by examples of electrical circuits and numerical examples.
