An adaptive reconfigurable flight control system using the mode switching of multiple models is studied. The conventional mode switching method may not guarantee the stability and the performance of the system. In this study, modified adaptive mode switching and decision logic are proposed to improve the adaptiveness of the transient dynamics of a system while maintaining the stability of the c...

The Multi-functional Variable Refrigerant Flow (MFVRF) system is designed to realize simultaneous heating and cooling for temperature regulation of individual zones by allowing the heat exchangers of both indoor and outdoor units to operate as an evaporator or condenser. It is thus desirable to use measurements readily available on the MFVRF system to determine switching between different modes...

in order to establish the appropriate methane fermentation technology for low strength wastewater, a 2.0 l egsb reactor was operated at 20â°c with 0.3 - 0.4 g cod/l of sucrose-based synthetic wastewater for 500 days. at the start up period, the reactor was operated in egsb mode with a 5 m/h up flow velocity by continuous effluent recirculation. however, the egsb reactor exhibited insufficient c...

This paper presents a new analytical model for calculating burst loss rate (BLR) in a slotted optical burst switched network. The analytical result leads to a framework which provides guidelines for optical burst switched networks. Wavelength converter is used for burst contention resolution. The effect of several design parameters such as burst arrival probability, wavelength conversion capabi...

Stochastic switching is an example of phenotypic bet hedging, where an individual can switch between different phenotypic states in a fluctuating environment. Although the evolution of stochastic switching has been studied when the environment varies temporally, there has been little theoretical work on the evolution of phenotypic switching under both spatially and temporally fluctuating select...

Reduced switching loss favours Pulse Skipping Modulation mode of switching dc-to-dc converters at light loads. Under certain conditions the converter operates in discontinuous conduction mode (DCM). Inductor current starts from zero in each switching cycle as the switching frequency is constant and not adequately high. A DC-to-DC buck converter is modelled and simulated in this paper under DCM....

This paper we proposed advanced burst mode control technique to reduce the standby power consumption of the switch mode power supply (SMPS). To reduce the standby power consumption, most of the converter use burst mode or skip mode control technique. However Conventional standby mode control techniques have some problems such as audible noise and poor regulation. In proposed techniques, basical...
