摘　　要：为了克服物理实验系统的局限性,充分利用MATLAB/Simulink仿真软件的优势,分析了采样开关、采样周期、采样保持器对采样系统性能的影响.仿真实验结果表明了采样开关对常规系统和大惯性系统的影响是有差异的,采样周期的合理选择是影响系统性能的一大因素,而保持器虽能复原信号但降低了系统的稳定性.虚拟实验实现了理论知识到实践知识的转化,为设计性能优良的采样系统提供依据.In view of the limitations of physical experiment system,this paper makes full use of the advantage of MATLAB/Simulink simulation software to analyze the effect of the sampling switch,sampling period and the sampling retainer on the performance of the sampling system.The results of simulation experiments demonstrate that the sampling switch has a different influence on the conventional systems and on the big inertia systems.Reasonable choice of sampling period is one of the main factors affecting the system performance,and the retainer is able to recover the signal but decreases the stability of the system.The virtual experiment realizes the transformation of the theoretical knowledge into the practice knowledge and lays the foundation for the design of sampling system with excellent performance.
