In recent data centers, a system manager has become able to access data in servers such as equipment temperatures, power consumption, fan rotation speeds and computational loads. The technological advance would allow one to model the cooling process more accurately and to feedback online data to control algorithms for air conditioning units, which would contribute to enhancing energy efficiency for the cooling system. In this paper, we first model the cooling process based on the above data and then formulate an optimization problem to be solved at a certain time interval to determine the reference set-point of the air conditioning units. The real-time optimization scheme is then demonstrated on a real data center cooling testbed.","PeriodicalId":416828,"journal":{"name":"Transactions of the Society of Instrument and Control Engineers","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131661821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nonaka","doi":"10.9746/SICETR.55.156","DOIUrl":"https://doi.org/10.9746/SICETR.55.156","url":null,"abstract":"In this study, the automatic tuning model error compensator (AT-MEC) is proposed. MEC is one of the two-degree-of-freedom control methods to suppress the influence of the model error. This compensator has sim-ple and general structure, and is easy to be implemented. However, there is no systematic tuning method for compensation gain for multi-input multi-output nonlinear systems. In this paper, the fictitious reference iterative tuning (FRIT) method is applied as on-line adjustment method of MEC. FRIT calculates the optimal value for parameters of a controller based on the deviation from a response of a reference closed loop model. By combinat-ing online tuning method to MEC, AT-MEC suppresses the influence of fluctuating model errors. In addition, to extend the applicability of the AT-MEC, the exact linearization technique is introduced to AT-MEC. As the result, the proposed method works for the fluctuating model error of a number of MIMO nonlinear systems. In this paper, the validity of this proposed method is verified by the experiment of an automatic driving vehicle.","PeriodicalId":416828,"journal":{"name":"Transactions of the Society of Instrument and Control Engineers","volume":"626 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115107582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this research, we pro-pose a hybrid eye tracking method using an RGB-IR camera, which can capture a color image and a near-infrared image simultaneously, to compensate for the weakness of each technique. Pupil detection can be worked better than iris detection because the eyelid often occludes iris. On the other hand, iris area can be used for model fitting because iris size is constant. Therefore, the hybrid eye tracking method works as a glint-free model-based approach in our proposed method. The model fitting can be automated as initialization, and the relationship between the 3D eyeball model and eye camera is solved. Additionally, 3D eyeball pose can be estimated without using first Purkinje image, and the pupil size can be measured quantitatively. We evaluated the accuracy of the estimated point-of-gaze and the pupil size, and we confirmed the feasibility of the proposed method through experiments.","PeriodicalId":416828,"journal":{"name":"Transactions of the Society of Instrument and Control Engineers","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117061068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the FF controller, the model is linearized in the real-time operation and the inverse model is obtained from it. The control performance is evaluated by the 2I2O control test, where the interval of 1st and 2nd main heat release rate peak and the ratio between 1st and 2nd heat release rate peak are controlled by operating 2nd main injection timing and its quantity. The control system showed good performance in the reference following test.","PeriodicalId":416828,"journal":{"name":"Transactions of the Society of Instrument and Control Engineers","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121943928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
