Taken the high voltage SF6 circuit breaker (HV SF6 CB) as the research object, a novel axial vortex chamber structure with an “X-type” guide blade constructed at the nozzle is proposed to exchange the energy of the turbulent gas flow in the radial direction during the interruption and to control the gas flow temperature gradient. The 3D flow field physical and mathematical model of the arc quenching...
This paper presents a hierarchical inner-outer loop-based approach to the longitudinal and lateral control of a small unmanned helicopter in the presence of parameter uncertainties and exogenous disturbances. The outer loop employs robust H∞ output feedback to attenuate the wind disturbance and track the reference trajectory, while the inner loop controller is proposed to solve the parameter uncertainties...
