(2016) 23: 1085-1094 DOI: 10.1007/s11771-016-0358-7 Diving control of underactuated unmanned undersea vehicle using integral-fast terminal sliding mode control YAN Zhe-ping(严浙平.... To stabilize the vertical motion system, the surge velocity and the depth control controllers were proposed using backstepping technology and an integral-fast terminal sliding mode control (IFTSMC......
the controlled plant and its mathematical model. Section 3 designs the adaptive fuzzy integral sliding mode control (AFISMC) feeding pressure controller for CFS. In section 4, experiments are conducted on a TC...J. Cent. South Univ.

an arbitrary fluorescent color. Further, the CCFL has longer lifetime expectancy than a hot cathode fluorescent lamp and requires only a simple lighting circuit. Further, the CCFL shows a negative resistance..., an independent model of cold cathode fluorescent lamp (CCFL) driving circuit is used to conduct simulations, leading to a precise modeling. A library is configured through modeling and its accuracy......
in the slag meet the national emission standard. Besides, the sulphur content in the obtained Fe-Cu alloy is low to 0.03 wt%. Key words: copper slags; waste cathode carbon; oxidative desulfurization... and is far less than the national allowable emission concentration in China. 3) As the amount of waste cathode carbon increases, more iron and copper could be reduced and then transferred into the metal......
