A timed control synthesis approach is proposed for a class of hybrid systems modeled with rectangular hybrid automata. The control objective is to constrain the reachable state spaces by the addition of control specifications which can be inconsistent with the system dynamics. Our approach is within an automatic control view and is based on the offline computation of the system new transition g...

in the present paper, the idea of braking energy regeneration and reusing that energy during acceleration for a refuse truck is comprehended. according to their driving cycle, the refuse trucks have a good potential for braking energy regeneration. on the other hand, hydraulic hybrid is a powertrain with high power density which is appropriate for energy regeneration. in the primary stage of th...

High-power microwave amplifier operation has been studied for use in a number of applications. The performance of the amplifiers has been marred, in some cases, by pulse shortening of the microwave signal. A possible source of the shortening is the loss of the beam due to hybrid HEM11 mode interaction with the beam. In this paper, we describe experiments which investigate high-power operation a...

ferent species is a process called hybridization,with the offspring known as hybrids. Probably the best recognized animal hybrid is the mule,which is a cross between a female horse and a male donkey. Hybrids can have some characteristics of both parents. Breeding hybrids with selected or favored characteristics of each parent is one of the goals of animal husbandry. When a hybrid has characteri...

Dynamic modeling and control of dc-dc series resonant converter (SRC) especially when operating in discontinuous conduction mode (DCM) is still a challenge in power electronics. Due to semiconductors switching, SRC is naturally represented as a switched linear system, a class of hybrid systems. Nevertheless, the hybrid nature of the SRC is commonly neglected and it is modeled as a purely contin...

Regular wave-induced behaviour of a floating stationary two-dimensional body with a moonpool is studied. The focus is on resonant piston-mode motion in the moonpool and rigid-body motions. Dedicated two-dimensional experiments have been performed. Two numerical hybrid methods, which have previously been applied to related problems, are further developed. Both numerical methods couple potential ...

The present study aimed at ranking and selecting the superior geothermal project for hydrogen production in 14 provinces of Iran using a multi-objective optimization fuzzy hybrid approach through analyzing the ratio (fuzzy Moora) and expanded entropy weighting method. In this research, the extended entropy weighing method and the Fuzzy-Moora approach were utilized to weigh the criteria and proj...

The hybrid system composed of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC) is considered. Two operation modes, the unit-power control (UPC) mode and the feeder-flow control (FFC) mode, can be applied to the hybrid system. Renewable energy is currently widely used. One of these resources is solar energy. The photovoltaic (PV) array normally uses a maximum power poin...
