    In this paper describes the speed output of DC motor. The DC motor is controlled by DC converter which is using the PLL controller. This proposed is designed and implemented the current output of the DC-DC chopper which fed to DC motor based on close-loop control. The close-loop control is obtained the small signal from the tachogenerator and encoder. The encoder is converted the small signal to similar PWM waveform feedback to PLL detector that is adjusted the PWM signal driven into DC chopper. In order control to applied high precision speed of DC motor.

    This paper presents implement in speed control of a separately excited DC motor using fuzzy logic control (FLC) based on Lab VIEW (Laboratory Virtual Instrument Engineering Workbench) program. Lab VIEW, is a graphical programming environment suited for high-level or system-level design. Therefore, the principle that are data flow model, different from text-base programming and a sequential model. The user-friendly interface and toolbox design are shown the high level of suitableness and stability of Lab VIEW and fuzzy logic on speed control of DC motor. The fuzzy logic controller designed to applies the required control voltage that sent to dc motor based on fuzzy rule base of motor speed error ( e ) and change of speed error (ce). The results show the control as a FLC that do the comparison with PI and PIP Controller. © 2006 ICASE.
