本课题主要是在Simulink环境中对双闭环直流调速系统进行仿真设计，具体内容有：对电流调节器和转速调节器进行校正设计；对电流环和转速环进行时域和频域分析；对调速系统进行跟随性和抗扰性分析。(This issue is mainly in the Simulink environment on the Double Loop DC Speed Control System simulation with the specific content: The current regulator and speed regulator for correct design of the current loop and speed loop time domain and frequency domain analysis swap speed system and immunity following analysis.)

The codes are the matlab platform. they are begin simple to complex.
