  • Fatigue Driver Detection System Using a Combination of Blinking Rate and Driving InactivityFatigue Driver Detection System Using a Combination of Blinking Rate and Driving Inactivity

    According to the results, the graph analysis on ten sets of 1-minute samples show that the typical blink of human contains alternating inter-blink periods of shorter and longer durations depend on the driver’s state. Although the results show that our method works well for the images taken under controlled environments and changes of illumina...

  • DC Model-Based IMC Method for Brushless DC Motor Speed ControlDC Model-Based IMC Method for Brushless DC Motor Speed Control

    With the novel improvement of using DC motor model-based in Forward and Inverse Model, the new IMC system for BLDC speed control is much less amount of calculation than the classical IMC model based on BLDC motor. The results show that all the advanced features of the traditional IMC model are considerably remained in the developed IMC system...

  • Studying the Effect of Facility Size on the Selection of Automated Guided Vehicle Flow ConfigurationsStudying the Effect of Facility Size on the Selection of Automated Guided Vehicle Flow Configurations

    The study shows the effect of AGV flow configurations on the RUTT values of AGVs. It also highlights the dependence of the results on the number of stations and facility layout used. In summary, in small sized facilities the traditional configuration performs the best with respect to RUTT values. All configurations act almost the same in inte...

  • A New Method to Design Optimal Power Compensator in Hybrid Electric VehiclesA New Method to Design Optimal Power Compensator in Hybrid Electric Vehicles

    The paper proposes a new method to compensate power for HEV as SPH mode. The new feature is using electrical equipment without mechanic of pedal. By doing that, the safety of the HEV can be increased and the life time of HEV can be extended also. The proposed algorithm can be applied in practice in factories of HEV.

  • Design of Sliding Mode Controller for the 2D Motion of an Overhead Crane with Varying Cable LengthDesign of Sliding Mode Controller for the 2D Motion of an Overhead Crane with Varying Cable Length

    In this study, we successfully designed a sliding mode controller for a complicated operation of an overhead crane: simultaneously combining control of cargo lifting, trolley moving, and cargo swing vanishing. From the simulation and experiment results, all system responses are asymptotically stable: cargo swing completely vanished and trolle...
