摘　　要：本文建立了他励直流电动机虚拟模型,通过模型进行仿真算法分析,并利用虚拟技术,在仿真平台上实现仿真,在上位机上显示数据,对单闭环直流调速系统进行可行性研究与优化。仿真做的主要前期工作为模型建立,通过电枢回路方程和动力方程进而推导出电动机的数学模型方程,并对模型进行分析计算。后期工作对所建立的模型进行仿真,并调试出模型数据,进而得到仿真结果。设计的虚拟模型建立在虚拟仿真平台上,利用平台的模拟和数字输入输出端口进行信号的采集和传递,并利用仿真平台强大的内部资源进行运算分析,从而达到期望的研究效果。A virtual model of excited DC motor is established in this paper. With the help of model simulation algorithm analysis and the virtual technology, simulation on simulation platform, displaying data on PC, study on the feasibility and optimization of single closed loop DC speed regulating system are realized. The main preliminary work of simulation is building model, in which the mathematical model equations of motors are derived from the armature circuit equations and dynamic equations., and the analysis and calculation of model are completed. The later works are to simulate the established model, debug the model parameters, and then get simulation results. In this paper, the virtual model is built on a virtual simulation platform, analog and digital I/O ports of the platform are used for collection and transmission of signals, and powerful internal resources of simulation platform are adopted for computation and analysis to achieve the desired research results.
