Hybrid excavator control strategy based on rules optimizes the specific fuel consumption only to determine engine operating point in the perspective of qualitative analysis, it is not sufficient to reduce the excavator fuel consumption because of ignoring the affect of engine power output. In this paper, an instantaneous minimum fuel consumption control strategy for hybrid power-train is propos...

simultaneous routing and resource allocation has been considered in wireless networks for its performance improvement. in this paper we propose a cross-layer optimization framework for worst-case queue length minimization in some type of fdma based wireless networks, in which the the data routing and the power allocation problem are jointly optimized with fuzzy distributed h∞ control strategy ....

In wireless networks, a widely studied approach is to minimize transmit powers subject to some quality-of-service constraints. Minimizing transmit powers however is not equivalent to minimizing the energy consumption. In wireless sensor networks that operate in a low-rate regime, the discrepancy between power consumption and the overall energy consumption is even more evident since the energy e...

application of appropriate agricultural operations is a strategy to reduce energy consumption and greenhouse gas emissions from agricultural productions process. in this study, fuel consumption and greenhouse gases emissions values for each farm operation was evaluated in gorgan and ali-abad katol to soybean product. all activities and production processes about operations were monitored and re...

This paper presents the application of an active energy management strategy to a hybrid system consisting proton exchange membrane fuel cell (PEMFC), battery, and supercapacitor. The purpose is control battery supercapacitor states charge (SOCs) as well minimizing hydrogen consumption. Energy should be applied systems created in this way increase efficiency working conditions. In study, optimiz...

Energy management in electrified vehicles is critical and directly impacts the global operating efficiency, durability, driveability, safety of vehicle powertrain. Given multitude components these powertrains, complexity proper control significantly higher than conventional internal combustion engine (ICEV). Hence, several algorithms numerical methods have been developed implemented order to op...

This paper presents an adaptive equivalent consumption minimization strategy (ECMS) and a linear quadratic tracking (LQT) method for optimal power-split control of combustion engine electric machine in hybrid vehicle (HEV). The objective is to deliver demanded torque minimize fuel usage service brakes, subject constraints on actuator limits battery state charge (SOC). First, we derive function ...

In recent years, the development of hybrid powertrain allowed to substantially reduce CO2 and pollutant emissions vehicles. The optimal management such power units represents a challenging task since more degrees freedom are available compared conventional pure-thermal engine powertrain. priori knowledge driving mission allows identifying actual control strategy at expense quite relevant comput...

Propulsion system electrification revolution has been undergoing in the automotive industry. The electrified propulsion improves energy efficiency and reduces dependence on fossil fuel. However, batteries of electric vehicles experience degradation process during vehicle operation. Research considering both battery consumption battery/ultracapacitor is still lacking. This study proposes a Q-lea...

In this paper, a novel Equivalent Consumption Minimization Strategy (ECMS) is developed for a series hybrid powertrain system, based on the flow of energy through energy sources and components. The performance of the controller is assessed using both urban and highway drive cycles, through comparing results for the series hybrid powertrain system against a comparable conventional powertrain.
