摘要
本论文是基于直流调速系统的设计与仿真，通过对控制系统的硬件电路设计实现对控制系统的功能构成的进一步了解，并利用Matlab／Simulink工具箱进行系统的动态仿真从而分析转速和电流的仿真波形，并进行调试，使双闭环直流调速系统趋于完善、合理．
采用工程设计方法对双闭环直流调速系统进行辅助设计，选择调节器结构，进行参数计算和近似校验．并建立起制动、抗电网电压扰动和抗负载扰动的Matlab／Simulink仿真模型．其中电路的设计包括转速显示电路、转速检测电路、电流检测电路、触发脉冲输出电路、过零检测电路以及保护电路。
通过仿真实现对系统的启动性能分析与抗扰性能分析，得出系统对负载的大幅度突变和电网电压的大幅波动具有良好的抗扰能力但是与理想的电动机的起动特性相比较，该系统的起动和恢复时间显得略长一些等结论

Abstract
This thesis is based on the DC speed control system design and simulation, through the control system hardware design to realize the control function of the system constitutes a further understanding Then the Matlab model of double closed - loop DC motor control system was built. The speed and current waveform were analyzed carefully. By trying a great deal of simulation the DC motor control system was made better and more reasonable.
According to engineering design method a double closed- loop DC motor control system was designed, a modulator structure was selected and computed, and its parameter was corrected. And establish a Matlab / Simulink simulation model which Include braking, anti-disturbance and anti-grid voltage load disturbance Circuit design, including speed display circuit, speed detection circuit and current detection circuit, trigger pulse output circuit, zero crossing detection circuit and protection circuit.
we conclude that this Significant mutation system load fluctuations and grid voltage has a good disturbance rejection capabilities by Simulationt System start-up performance analysis and performance analysis of disturbance rejection but also could find that the Ideal motor starting characteristics compared to the system start-up and recovery time seems even longer and so on
Key words: Regulator; double closed- loop DC motor control system; Matlab/Simulink
