Stability analysis of semistate system and the application to nonlinear time-varying unforced RC

In this paper, the stability of semistate system is analysed from the viewpoint of stability of system motion, and the criteria on stability of nonlinear non-autonomous semistate system is given by using Lyapunov-like function similar to ordinary differential equation. Moreover, stability of nonlinear time-varying unforced RC system is obtained by the result given.
