It can also control MIMO system and treat constraints easily. However MPC has a disadvantage which is a big computational cost. MPC is successfully applied in the chemical industry, where the sampling period is sufficiently large, e.g., several tens of second or longer. However, MPC is not suitable for mechanical systems controlled with a sampling period in the order of milliseconds. So, in this paper, a feedback compensation method for discrete nonlinear systems is proposed to overcome the problem. To verify the effectiveness of the proposed method, a discrete time identified SI engine model is used for a simulation, and it is shown that computational time of the proposed method is faster than a conventional method, i.e. C/GMRES.","PeriodicalId":412987,"journal":{"name":"2015 54th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"303 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115216487","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}

The design objective is to determine a controller which maximizes the absolute value of the rate of change of the system's load (thereby maximizing the size of the possible set in some sense) while keeping the frequency deviation within its prescribed bound for all possible disturbances. In conjunction with the notion of conditionally linear model, the generation rate is required to stay within its linear range of operation for all possible disturbances. Consequently, the linear models of the systems are ensured to exist and, more importantly, theories for linear systems can be conveniently utilized. Using the known design framework consisting of the method of inequalities and the principle of matching, the design specifications are expressed as a set of distinct inequalities that can be solved in practice. The numerical results clearly illustrates the effectiveness and the usefulness of the framework adopted here.","PeriodicalId":412987,"journal":{"name":"2015 54th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124960244","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 such an application, high efficiency and high power density are the major driving factors that naturally require a high switching frequency. The SiC-MOSFET is widely considered a desirable switching device for the high-frequency power conversion/inversion circuits due to its high voltage, low on-resistance, and fast switching speed. Here a 700-V 40-kW isolated bidirectional resonant LLC DC-DC converter is designed and fabricated using both the conventional Si-IGBTs and SiC-MOSFETs. The experimental results show the DC-DC converter using SiC-MOSFETs can reach a system efficiency around 98%, about 2% higher than that of the DC-DC converter using the conventional Si-IGBTs at rated power. It is also found that high-power and high-frequency transfer such as working at 100 kHz is now not commercially available. The optimized design and fabrication of the high-frequency transformer is crucial to promote the application of SiC-MOSFETs in high-power isolated DC-DC converters. Besides, accurate modeling of the SiC-MOSFET, high-precision simulation of the converter, and cost-performance evaluation/prediction are also important.","PeriodicalId":412987,"journal":{"name":"2015 54th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122042400","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}
