Based on metrology, Geometrical Product Specifications (GPS) standard system proposes higher specification requirements for position tolerance evaluation. Based on analyzing of the definition of the axis of the plane and the measurement method, the least square method of parallel evaluation model is used for the model coordinate system transformation, so it can unify the elements of the tested elements...
The character of gas moving and air flow in heading laneway of underground coal mine was analyzed. Moreover, conventional double fuzzy control model was found to carry out two work mode, normal ventilation and gas discharging. In order to enhance the learning capabilities of the system to the environment, self-learning fuzzy model for auxiliary fan was built to tackle with normal ventilation and gas...
The inter-turn short circuits fault of field windings is one common fault in generators. It will cause serious damages if such faults are not handled properly in time?For this reason, according to the multi-loop method of AC machines this paper proposes multi-loop mathematical model of turbine generators with inter-turn short circuits fault of field windings. The inductance parameters are calculated...
