For the complexity and multiformity of leakage faults of mine, the fault information has the uncertainty. With the capability of the solving the uncertain problem, Rough Sets theory can determine the fault timely and accurately. The paper adopted Rough Sets to extract the attribute characteristics of leakage fault signal and then to build the decision(More)
A simulation system of direct torque control speed adjustment is introduced, it include field-weakening control. The simulation system reaLized induction-motor speed control within full-speed regions, constant torque adjustment less than foundation speed and constant power adjustment greater than foundation speed. The results of simulation show that system(More)
In this paper a wheeled mobile robot and multi-sensors fusing technology are introduced based on the embedded controller of the S3C2410. The function modules of the robot with avoiding obstacle, automatically tracking are analyzed. The ultrasonic ranging, image tracking, and speed detection cirCuits are designed, which adopted multi-sensor fusing(More)
