摘　　要：在分析闭环调速系统的结构与工作原理的基础上,利用Simulink建立了系统的仿真模型,给出了参数设置,利用仿真结果综合分析、比较了闭环调速系统在不同的转速给定值、不同的放大系数、不同的调节器和有、无电流截止负反馈情况下起动与加载的动态调节过程,并对其调速性能进行了分析与比较。仿真结果验证了调速系统仿真模型的可行性。The principles of speed control system with steady error,non-static error speed control system,current cut-off negative feedback speed control system are introduced merely in traditional materials. It is difficult for new learners to understand and grasp them thoroughly. Based on the analysis of these speed control systems＇ structure and basic working principles,the Matlab / Simulink simulation model of the speed closed-loop control system is established. The simulation parameters are given in detail. On different speed setpoints,different amplification factors,different regulators,with or without current cut-off negative feedback,DC speed control system can be simulated respectively. The dynamic adjustment process is analyzed and compared comprehensively with simulation results. The practicality of the simulation model is verified by the simulation waveforms. The teaching effectiveness and teaching quality have been improved by this kind of virtual experiment.
