Temperature plays a prominent role for living beings in the earth. People from various countries use to survive with different temperature based on the location of the country in the globe. Agriculture mainly depends on different temperature for crop cultivation and plantations. Many wildlife animals habituated to survive with particular temperature. Keeping all those things on hand, it is an impressing need to have an strong temperature maintenance system in order to bring the different temperature for the survival of different living beings in any location in the world. The artificial intelligence based on control algorithms having an inherent quality of automatically satisfying the above need with minimum human intervention is deisgned in this paper. It can be applied to the hotels, resorts and wild life sanctuaries to maintain artificial environment setup.

As an effort to develop more efficient system for an excavator, EH(Electro-Hydraulic) system has been widely adopted to take the advantage of the well-commercialized EH valves and its control technologies[1]. Utilizing the EH technology, an innovative IMV(Independent Metering Valve) control system for an excavator mechanism, which consists of high capacity EH valve blocks, an electric-controlled pump, and a main controller unit, has been developed by Hyundai Heavy Industries Co., Ltd. This IMV control system can provide tremendous flexibility to the control of cylinder movements and reduce the energy consumption of an excavator. In this paper, we introduce the major features of the developed IMV control system and propose the novel control algorithm considering optimal power distribution and energy saving. Furthermore, the effectiveness of the proposed system and control algorithm is verified through various experiments conducted on an excavator equipped with the IMV control system. The results are compared with those of conventional machine. It was shown that IMV system could save the energy consumption more than 10% of an excavator.

This paper presents a new method for optimizing mobility of a 4x4 hybrid-electric vehicle through control of wheel power distribution. First, a mobility index is used to calculate optimal power distribution for improved mobility using a Lagrangian multiplier. A control algorithm is developed for altering the wheel power distribution in order to follow a trajectory path which is calculated for optimum mobility. An inverse vehicle dynamics math model of a 4x4 vehicle is used in which a task is assigned as a required velocity to test in two simulated curvilinear maneuvers.

Multi-axle land vehicles with independent drive actuation on multiple axles offer improved stability and traction on various road surfaces. This is possible by exploiting the redundancy of the drive system to generate additional yaw moment and to maximize the utilization of individual tire-road contacts without significant extra power consumption by the drive motors. This paper aims at improving the efficiency of torque allocation with the addition of active steering while enhancing the dynamic performance of the independent hub motor driven multi-axle vehicles. The control algorithm outlined here employs a two level scheme. The higher level computes the desired global control efforts that are needed to track the reference yaw rate and slip angle state responses generated by a reference vehicle model, and the lower level executes optimal control allocation with a cost function that simultaneously takes into account I) maximization of the tire utilization on all axles considering dominant tire nonlinearities, and 2) minimization of the actuation efforts of the active steering system and the distributed motor torques. The validity of the proposed algorithm is verified via comparison of the simulations of the control allocation scheme applied to a high fidelity multi-axle vehicle under several aggressive test maneuvers with different actuation configurations. The results suggest that the addition of active steering provides lower actuator power consumption and tire usage while ensuring enhanced lateral and longitudinal dynamic performance for the vehicle.

The effect of time-of-use tariffs on the demand response flexibility of an all-electric smart-grid-ready dwelling

引用

ENERGY AND BUILDINGS 2016年第0期128卷 56-67页

作者： Pallonetto, Fabiano Oxizidis, Simeon Milano, Federico Finn, Donal Univ Coll Dublin Elect Res Ctr Room 338Engn Bldg Dublin 4 Ireland Tyndall Natl Inst Int Energy Res Ctr Cork Ireland Univ Coll Dublin Sch Elect & Elect Engn Dublin Ireland Univ Coll Dublin Sch Mech & Mat Engn Dublin Ireland

The paper is concerned with the development and evaluation of control algorithms for the implementation of demand response strategies in a smart-grid enabled all-electric residential building. The dwelling is equipped with a 12 kW heat pump, a 0.8 m(3) water storage tank, a 6 kW photovoltaic (PV) array, solar thermal collectors for domestic hot water heating and an electric vehicle. The building, located in Ireland, is fully instrumented. An EnergyPlus building simulation model of the dwelling was developed and calibrated using monitored data from the building. The developed model is used to assess the effectiveness of demand response strategies using different time-of-use electricity tariffs in conjunction with zone thermal control. A reduction in generation cost (-22.5%), electricity end-use expenditure (-4.9%) and carbon emission (-7.6%), were estimated when DR measures were implemented and compared with a baseline system. Furthermore, when the zone control features were enabled, the efficiency of the control improved significantly giving, an overall annual economic saving of 16.5% for the residential energy cost. The analysis also identified an annual reduction of consumer electricity consumption of up to 15.9%, lower carbon emissions of 27% and facilitated greater utilisation of electricity generated by grid-scale renewable resources, resulting in a reduction of generation costs for the utility of up to 45.3%.

This study reviewed VAV systems modeling and simulations, control strategies and optimization tools, the airflow characteristics of VAV systems, some common VAV systems' faults, detection and diagnosis, energy usage and analysis, and the current applications of variable air volume (VAV) air-conditioning systems. VAV system modeling is very complex as it involves complex structures and parameters a result of which has led to lack of models that combine both the AHU and building with all the required parameters. The most common controllers used in VAV systems are the PID controllers. We saw that supply air temperature and the flow rate of supply air are the best parameters that can be optimized in a VAV system. as they greatly minimize energy consumption. Genetic algorithms have good robustness, and, can be easily parallelized. However, they suffer from shortcomings such as slow convergence rates under some conditions, and have difficulty in adjustment of algorithms since there are no rules for determining the number of individuals in populations. FLCs boost of advantages such as less or minimum overshoot, oscillation and power consumption compared to conventional PID controllers, can be used in MIMO systems, and they do not require models as they can control non-linear processes. Airflow control in VAV systems can be achieved through controlling static pressure and position of the damper. Literature survey shows that balancing and distribution of airflow in VAV air-conditioning systems can be considered to be one of the main challenging areas of research concerning VAV system control. Most methods used today for detecting and diagnosing faults are hybrid. These are superior to the conventional methods of FDD. In conclusion, VAV air-conditioning systems are the most energy efficient systems in use today. Despite of their current strengths, VAV systems energy saving potential can still be improved.

JOURNAL OF ATMOSPHERIC AND OCEANIC TECHNOLOGY 2016年第9期33卷 2001-2013页

The computation of turbulent fluxes of heat, momentum, and greenhouse gases requires measurements taken at high sampling frequencies. An important step in this process involves the detection and removal of sudden, short-lived variations that do not represent physical processes and that contaminate the data (i.e., spikes). The objective of this study is to assess the performance of several noteworthy despiking methodologies in order to provide a benchmark assessment and to provide a recommendation that is most applicable to high-frequency micrometeorological data in terms of efficiency and simplicity. The performance of a statistical time window-based algorithm widely used in micrometeorology is compared to three other methodologies (phase space, wavelet based, and median filter). These algorithms are first applied to a synthetic signal (a clean reference version and then one with spikes) in order to assess general performance. Afterward, testing is done on a time series of actual CO2 concentrations that contains extreme systematic spikes every hour owing to instrument interference, as well as several smaller random spike points. The study finds that the median filter and wavelet threshold methods are most reliable, and that their performance by far exceeds statistical time window-based methodologies that use the median or arithmetic mean operator (-34% and -71% reduced root-mean-square deviation, respectively). Overall, the median filter is recommended, as it is most easily automatable for a variety of micrometeorological data types, including data with missing points and low-frequency coherent turbulence.

Sudden local severe weather is a threat, and we explore what the highest-end supercomputing and sensing technologies can do to address this challenge. Here we show that using the Japanese flagship "K" supercomputer, we can synergistically integrate "big simulations" of 100 parallel simulations of a convective weather system at 100-m, grid spacing and "big data" from the next-generation phased array weather radar that produces a high-resolution 3-dimensional rain distribution every 30 s two orders of magnitude more data than the currently used parabolic-antenna radar. This "big data assimilation" system refreshes 30-min forecasts every 30 s, 120 times more rapidly than the typical hourly updated systems operated at the world's weather prediction centers. A real high-impact weather case study shows encouraging results of the 30-s-update big data assimilation system.

Complex Fenestration Systems (CFS) incorporate a non-specular layer within the window assembly (e.g. undulated and perforated screens). CFS are often incorporated to the building facade for improving building thermal and visual performance. Thermal-lighting simulations of spaces with CFS are carried out with different tools. However, an integrated lighting and thermal analysis is a complex task to be implemented at the design stage of buildings that incorporates CFS. This paper presents mkSchedule, a new Radiance-based tool that allows the flexible and time-efficient generation of a schedule for the CFS position and luminaries power fraction. The methodology incorporates the three-phase method and use scripts written in Lua programming language. The schedule can be used for detailed thermal-lighting simulations. This work presents the application of this methodology to an office space, showing that the methodology is flexible enough to set different CFS and luminaries' controls, providing annual schedule in short computing time.
