摘　　要： 考虑了具有缓变输入信号的非线性动力系统的一类平衡点集合的稳定性。采用不同于相应文献的分析技巧,充分利用非线性系统右端项提供的信息,在较相应文献输入信号更弱的假设下,得到了由输入信号产生的轨线充分接近系统相应解的一些充分条件,放宽了该类控制系统设计中对输入信号的限制。并举实例说明结论的有效性。 Stability for a certain family of equilibrium of a nonlinear system with varying input signals was considered. Using analytic technique, which was different from the existing relevant methods in the literature, some sufficient conditions had obtained to guarantee that the trajectory, which was derived by input signals, was convergent to the relevant solution of systems under more general hypothesis and information of right term of the nonlinear systems. Here a more general class of input signal in nonlinear control systems was designed. An example was given to illustrate the new results.
