| 摘 要： | 基于对变增益非线性控制系统的研究,结合变增益函数 (-0.255ｅ0.3Usin(100πt))K的特点,运用Matlab6.5中的Simulink软件包建立仿真模型.对ｅ0.3U和变增益环节K组建子系统并封装，然后进行了相应的仿真分析.仿真结果表明，变增益函数(-0.255ｅ０．３Ｕsin(100πt))K，K在3种不同区间下的仿真输出是不相同的，充分反映了非线性控制系统的特点.由此阐述了控制系统中变增益环节K在不同取值区间下，对控制输出的影响.

| Abstract: | This paper studies the variant gain control of nonlinear systems,combining the features of variant gain function (-0.255 sin(100πt)) K.Simuli
nk of Matlab6.5 Software is used to establish a simulation model，packaging the subsystem of ｅ０．３Ｕ and K,illustrating the effect which K implies on the output system.The simulation output of k is three intervals is different,which shows the features of the non-linear control system.Therefore,in different value intervals,the influence of variant gain k on the output control is analyzed. |
