摘　　要：针对实际应用中Lyapunov函数不易选择,且随输入量的变化具有不定性的问题,利用积分不等式研究了二阶线性时变系统的镇定条件,给出了利用系数和输入量直接判定该函数稳定性的若干结论。经实例验证,这些结论的应用简单、有效。In view of the fact that the Lyapunov f change of input, the tranquilization conditions of with by means of integral inequality. Several con uction is not easy to choose and variational with the second-order linear time-variant systems were dealt clusions were given for determining the stability directly based on the coefficients and input quantity. An example was given to show the convenience and effectiveness of application of the conclusions.
