    A useful technique to reduce power consumption for cold rolling mill driven by large direct current (DC) motors in steel production industry is introduced. The proposed method is based on automatically stopping cooling units and shunt-field winding exciters of DC motors for operating the mill in maintenance mode and long-time stand-by mode. The smart relay modules and normally-closed contractors used for energy saving are controlled via an existing direct digital control (DDC) system. Performance of the proposed technique has been observed at a Sendzimir cold rolling mill using the stand driven by three couples of 2,150 kW DC motors in Thailand. Experimental results show that the proposed method provides saving in energy cost in a short payback period. © 2014 ISSN 2185-2766.

    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.

    DC motor control using CDM based two-degree-of-freedom controller for desired tracking and disturbance rejection characteristics
    (2012-12-01)
    Isarakorn, Don
    This paper focuses on a design of two-degree-of-freedom (2DOF) controller by Coefficient Diagram Method (CDM) for position control of a DC motor. It is known that the 2DOF control system can be designed to meet both tracking and disturbance rejection performances, which are the most important for the position control system. Nevertheless, it requires tuning of many parameters. The CDM is an efficient method in designing the parameters of 2DOF controller based on the stability and the speed of the controlled system so that the desired performance criteria can be met. By the proposed design method, the parameters of 2DOF controller for a DC motor control system are obtained properly without any adjustment. Furthermore, the tracking and disturbance rejection performances are simultaneously designed. The results reveal the versatility of the CDM tuning technique in the position control of a DC motor. © 2012 ICROS.

    This paper presents a technique to adjust and improve mechanical responses of DC Motor. The proposed technique uses math model for simulation to observe the transience and steady state response in no-load condition. Information derived from the simulation results can be applied to compensate the mechanical loss, inertia, viscous friction by feeding electrical energy. The test results of the compensation technique in this research can adjust and improve the response of speed and torque under reasonable tests. Moreover, this technique can apply to virtual load for Dynamometer. © ICROS.

    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.
