This paper studies the finite time attitude control of a satellite with flexible appendages when the velocity measurements are not available in the condition of external disturbances and model uncertainties. First a dynamic model which considers the coupling effect between the motion of the rigid hub and the deformation of the flexible appendages is build. Then a terminal sliding mode observer is...
There usually exist rubber materials in the outside of underwater navigators. In one aspect, sound radiation from these navigators can be reduced by the materials, and it is beneficial to control the pollution of noises in ocean environments. In the other aspect, the resistance induced by the fluid can be decreased, and it is helpful to enhance the speed of these navigators. In the paper, a numerical...
The rapid development of services leisure and entertainment industry is an important feature of industrial change in the last 20 years. For China, we are in the upgrading of the industrial structure and in the new economic growth, so to develop fully and promote the industry has a special significance. If your business always wants to keep the state of success, the innovation idea is very necessary,...
A modified voltage space vector pulse-width modulated (PWM) algorithm for three-phase four-wire distribution static compensator (DSTATCOM) is described in this paper. The mathematical model of shunt-connected three-leg inverter in three-phase four-wire system is studied in a-b-c frame. The p-q-o theory based on the instantaneous reactive power theory is applied to detect the reference current. A fast...
