This paper presents an analysis and design for simulation in Lab view, a fuzzy speed control of DC motor using the Mamdani algorithm. Shows the design of speed control on Mamdani type with seve membership functions, using the LaBVIEW graphical interface. Different processes are presented highlighting the most important issue in terms of idea creation, development and implementation of intelligent control. Finally, we present the results of each item taking into account the application and form of development for this purpose.
