Aim at the starting problem of the sensorless brushless DC motor, sensorless brushless DC motor based on the Matlab/Simulink studies the startup process, and puts forward an optimization scheme. According to the motor stator core saturation effects, with simultaneous input of 6 short-time pulse detection method of rotor position, and then determine the phase sequence to be driven, applied to the motor...
In this paper, a novel technique for human daily motion analysis and recognition is proposed. The technique is based on the use of inertial sensors, and integrates a longest common subsequences (LCSS) algorithm as the kernel function for support vector machines (SVM), which measures the similarity of human daily motion time-series. In our system, we use the wearable motion capture system to obtain...
Due to the special security requirements and abominable environment, researching in the high reliability of the communication network and power in coal mine monitoring system is become special important. The reliability of the communication network and power in the coal mine monitoring system has been studied. To assess the reliability of the underground power and communication network, the constant...
