A pulse width tunable passively Q-switched fiber laser is demonstrated by using a graphene saturable absorber (GSA) with graphene-covered-microfiber (GCM) structure. Due to the cross absorption modulation (XAM) effect in graphene, the modulation depth of the GSA could be varied from 3.22% to 2.16%%, which results in that the output pulse width and the repetition rate of the laser could be varied from...
In this paper, the simulink model of the Brushless DC Motor (BLDCM), which's the actuator of the Electro-Mechanical Braking (EMB) system, was established. And then, typical faults of the BLDCM were analyzed. These faults included the faults of the motor, the power transistor, and the Hall sensor. In addition, the detailed theoretical analysis of these faults simulation results and their effect on...
