in this paper, we try to use modeling based on singular perturbation theory, in order to control satellite attitude during the wide rolling angle maneuvering through nonlinear h∞ control strategy. differential equations describing dynamics of the satellite are presented first, and by choosing the appropriate dynamic model for actuators and based on the standard singular perturbation model, the ...

Decision support systems are intended to assist human decision makers. In complex, dynamic domains a proper task apportionment between the computer and the human decision maker largely dictates system success. Task apportionment is even more critical when exceptions are introduced into the system. We examine an airbase logistics scheduling and planning system, a complex and dynamic application ...

This paper proposes a hybrid switching technique for a domestic PV system with AC-module architecture. In this PV system, independent control of PV modules, which are directly connected to DC terminals of a single-phase cascaded multilevel inverter, makes module-level MPPT possible to extract maximum available solar energy, especially in partial shading conditions. As one of the main contributi...
