Yuya Tanaka,Yasuo Konishi,Nozomu Araki,Hiroyuki Ishigaki 제어로봇시스템학회 2008 제어로봇시스템학회 국제학술대회 논문집 Vol.2008 No.10

This paper proposes an effective control system for a container crane that takes into account disturbances such as a wind. For efficient crane operation, it is necessary to realize accurate positioning of cranes, to minimize oscillation of containers and to realize the fastest possible control time while they are being carried. The crane input is assumed to be a binary with maximum and minimum values for quick control. The entire crane system including the binary input is considered as a hybrid system. A hybrid system is a generic term for a system in which continuous and discrete dynamics exist together. We control the entire crane system using the Mixed Logical Dynamical (MLD) system. An MLD system, which is a representation method for a hybrid system, is used for the crane system. It is generally known that an MLD system can be controlled by Model Predictive Control (MPC). We confirm the effectiveness of the proposed technique through computer simulation of the crane.

In order to keep the data center server room temperature condition, cooling energy consumption has been rapidly increased as the increasing internal heat gain from the server devices. And the cooling units for server systems are fully operated to satisfy the indoor temperature condition, it results in the excessive energy consumption. There are many wastes of cooling energy which is caused by the structural problems in data center server room. For example, a leakage by the electric cable hole, mixing or recirculation of hot air from the hot aisle to the cold aisle, short circulation of the CRAC(Computer Room Air Conditioning), and others. So there are many strategies to reduce the waste of cooling energy in data center. In this study, cold aisle containment system and variable air volume system were proposed among the various strategies to reduce the energy cosumption. To verify the effectiveness of the energy saving system, test bed which is same with exist server room was set up in IDC(Internet Data Center) building and comparative experiments were carried out in actual conditions. As the result, in case of setting server room temperature 30℃, the server device inlet temperature exceeded 27℃ class 1 condition of the ASHRAE standard. But in case of setting server room temperature below 26℃, the range of inlet temperature of server system was 18~26℃ by cold aisle containment system. In case of variable air volume system and setting server room temperature 26℃, total energy saving was 19.8% to conventional cooling system. After all, variable air volume system and cold aisle containment system were proved to be the effective solution for energy saving cooling system.

주차정보시스템은 주차 대기시간을 줄이고 운전자의 편의를 증진시킬 수 있지만, 다수의 검지기, 표출장치, 제어장치등을 포함하는 특성에 기인하여 항구적인 전력을 소비하는 특징을 갖는다. 근래에 국내외에서 환경 친화적 그린 빌딩을 위한 저 전력 소비 형 주차정보시스템의 요구가 증대되고 있다. 본 논문에서는 가상 빌딩의 주차장을 대상으로, 소비전력 저감을 특징으로 하는 주차정보시스템을 설계하였다. 본 설계를 위한 주차검지기로는 기 상용화된 배터리방식 주차 검지기인 무선루프식검지기와 지자기방식 검지기를 적용하고, 시스템 구성 및 통신 네트워크, 운전자 정보서비스 시나리오, 배터리 수명 평준화 등에 대한 설계를 진행하였다. 이어서, 설계된 주차정보시스템의 운영 소비전력을 추정하고 이를 종래의 일반적인 초음파방식 시스템의 동작 소비전력과 비교 하였다. 또한, 주기적 배터리 교체비용을 고려한 전력유지비용을 환산하여 비교하였다. 7년의 배터리 교체주기를 기준으로 하였을 때, 설계된 시스템의 운영 소비전력은 기존 초음파센서 기반 시스템의 13% 수준으로, 전력 운영비용 환산 값은 기존시스템과 유사한 수준인 94.9%로 추정되었다. 본 연구의 시스템은 소비전력의 괄목할 만 한 경감에 따라, CO2발생의 저감을 기대할 수 있다. The parking guidance system can increase driver’s convenience with detailed parking information service, but it continuously consumes electrical energy with large amount of sensors, displays and control modules. With the increase of the demand for green and sustainable building design, it becomes a meaningful issue for parking guidance system to reduce operating power. This paper presents the preliminary design and estimated results of a parking guidance system which is optimized to reduce the power consumption mainly on detectors and displays. The system design is based on commercial wireless parking detectors, wireless-loop-detector and earth-magnetic-detector. We have performed system architecture design, communication network design, parking information service scenario planning, battery life regulation and at last operating power estimation. With the 7 years of battery replace cycle, the estimated result for power consumption of designed system was 0.33W/slot, which is 13% of the traditional system's estimation result. The estimated annual maintain cost was similar to the traditional ultrasonic sensor based system's. The low power operable designed system can be expected to reduce CO2 emission.
