摘　　要：在简单介绍直流调速系统的系统组成及双闭环直流调速系统中转速、电流调节器的参数变化对系统性能影响的基础上,利用MATLAB/simulink软件的仿真平台对直流调速系统进行精确仿真,通过分析仿真结果,对转速调节器中Kn参数变化对系统超调量的影响进行了深入讨论,并给出直流调速系统转速调节器参数变化规律,规律一:当Kn的取值增大时,σn的值减小,但是σn减小到一定程度时又随着Kn值的增大而增大;规律二:Kn在16～17时的σn值最小;规律三:Kn的取值范围为6～26,其最佳取值为16.4,最佳点并不是取值范围的中心点。The components of DC speed control system is briefly introduced,and the change of DC speed,current regulator parameters which have effect on the system performance is taken as the basic,DC speed control system is accurately simulated by MTALAB/simulink software.The change laws of speed regulator parameters in the DC speed control system is obtained by analyzing the simulation results to deeply discuss the change of Kn in the speed regulator which has the influence of overshoots.There are three laws.Firstly,the value of σn will decrease when Kn increases,but with σn decreases to a certain extent,it will increase with the Kn increasing;Secondly,the minimum value of Kn is 16 to 17;Finally,the range of Kn is from 6 to 26,and the best value is 16.4,it is not the center of the range.
