In this paper, a systematic design approach based on event driven method is investigated for a class of switching systems, and the switching control system is able to generate chaos at will from linear systems under the designed switching rules. To gain this target, structures of a class of linear switching systems are analyzed properly, as a consequence of analysis, the corresponding criteria ...

This report summarizes progress on Washington University’s Terabit Burst Switching Project, supported by DARPA and Rome Air Force Laboratory. This project seeks to demonstrate the feasibility of Burst Switching, a new data communication service which can more effectively exploit the large bandwidths becoming available in WDM transmission systems, than conventional communication technologies lik...

A novel application and generalization of sigma–delta ( ) modulation has emerged in three-phase power-electronic converters. A conventional modulator with scalar signals and binary quantizer is generalized to a modulator with vector signals and a hexagonal quantizer. Indeed, power-electronic switching states may be thought of as determining the quantizer outputs. The output spectrum is a key pe...

Many multipoint virtual circuit switching systems have been proposed for use in ATM networks. The inherent exibility of ATM networks and the desire to use them for a wide range of diierent applications makes it impractical to rely upon statistical traac models, motivating a renewed interest in nonblocking networks. While the various multipoint architectures can all be conngured to be nonblockin...

Multiple-evaporator/vapor compression cooling systems are used for air conditioning in multi-zone buildings with a refrigerant supplied to each individual zone-evaporator from a central compressor/condenser unit. Such systems, incorporating controlled electronic expansion valves associated to each evaporator and a variable-speed compressor, allow the overall system to be able to operate in diff...

performances of electronic and mechanical draft control systems on a mf399 tractor were the objectives of the study to be evaluated and compared under field conditions. hence, the effects of two draft control systems (mechanical and electronic) under four ground speed levels and three set values of draft levels on rear wheel slippage, fuel consumption, compressive force within the top link and ...

switching supervisory is the most important section of a feedback control process inmimo hybrid systems. by choosing a non-compatible controller, system may go tounstable mode or high overshoot response. in this paper, a new method of switchingfor selecting mbc controllers is discussed. results of the simulation show the mimo(2-in 2-out) linear hybrid system can be switched stable and low overs...

This proposed work aims at forming a switching level modeling of Unified Power Flow Controller (UPFC) and analyzing its operation. The switching level modeling of UPFC is carried out using high power electronic devices such as IGBT based six pulse shunt and series converters. The operating performance of UPFC is demonstrated on Single Machine Infinite Bus (SMIB) system for different case studie...

In the paper a bi-directional power electronic interface based on an inductive coupled contactless energy transfer system for plug-in vehicles with Vehicle-to-Grid (V2G) capability is presented. To minimize the total losses of the system, a series resonant compensation circuit is applied assuring Near to Zero-Current Switching (N2ZCS) condition for insulated-gate bipolar transistors. The analyt...

Fast optical switching (μs timebase) is realized by using a RF frequency tone inserted in the optical packet that carries a digital payload. By using a highly selective RF filtering for optical packet header frequency recognition, we have obtained excellent performance in optical switching function.. The RF header is detected at optical node input, and signals the node switching control, which ...
