摘　　要：时变线性系统是信息处理相关课程教学的扩展内容,而其解往往不能写成解析解的形式,因而其数值解法是教学与科研中的一个基本问题.利用状态空间分析法,以实现对时变线性系统的系统建模,利用计算机虚拟仿真技术,可直观便捷地完成系统的虚拟仿真并得到其系统响应的数值解.在Matlab/Simulink图形交互式之虚拟仿真环境中,进行了时变线性系统的系统建模与虚拟仿真设计与实验.实验结果表明,其仿真建模过程直观明了,可操作性强,求解方法便捷可行.It is usually difficult to obtain analytical solutions for the linear time-variant system（LTVS）which is an extended content in signal processing courses,and then numerical methods of the LTVS is one basic issue in science and teaching.Based on the state space analysis,modeling and virtual simulation for a LTVS as well as its numerical solution for system response can be achieved in one convenient and vivid way by employing the basic blocks in the Matlab-Simulink.The Simulink-based simulations show workability of the presented method.
