The contents include DC motor structure and working principle of the analysis, structure analysis of DC speed control system, analysis of the advantages and disadvantages of the traditional control scheme, the establishment of the model of DC speed control system and fuzzy controller, fuzzy controller design and Simulink toolbox is used, and in the PID control and fuzzy control of DC speed control system simulation model of the output results and with the traditional control scheme, we can draw the conclusion that. Method in MATLAB are established simulation diagram of DC motor and DC speed regulator system, system of each module corresponds to the optimal parameter settings, first in DC speed regulating system with the traditional PID controller by simulation, the corresponding dynamic and steady-state performance and anti-disturbance kinetic energy force related data. The fuzzy rule, using the rules for fuzzy reasoning and fuzzy decision-making to get control of the actual situation of the DC motor speed conversion, set the parameters, a fuzzy controller is established, and then the DC speed control system PID controller is replaced by fuzzy controller, each part of the cascade system and maintain the original parameters unchanged, view the output waveform, recording data, comparative analysis the indicators. The research shows that the DC speed regulating fuzzy control system has the advantages of sim
