Abstract：This paper researched the controller of PID and fuzzy used by DC motor．First the paper simulated the PID control of DC motor and gained predictional results. According to the regulation parameters of PID Control was complicated owing to the large scale of the change in parameters, this text adopted controller based on generic algorithm that greatly simplified the rectify course to adjust parameter. Finally, this paper analysised fuzzy self control of DC motor．By simulation，it showed that the fuzzy controller was better characterized not only by its qualities of dynamical and stational but also anti-disturbanceand adaptivities to the changing parameters．
