摘要
本文放宽了稳定性定理中V定正和dv/(dt)常负的要求,V和dv/(dt)均可以是变号的,从而推广了稳定性定理。
In this paper, it is shown that the positive definiteness of liapunov function V and the nonpositiveness of dv/dt are not necessary, and the stability of a system can be determined by Vand dv/dt with variable signs, thus the liapunov′s stability theorem is spreaded.
