A decoupling control method named as neural network inverse system (NNIS) was presented for the radial suspending model of bearingless induction motor. Aimed at the nonlinear and strongly coupled characteristics, the model is analyzed with reversibility and proved to be reversible. The multi variable, strongly coupled, nonlinear system was dynamic decoupled into two linear displacement subsystems by connecting a NNIS before the bearingless induction motor. Then the two decoupled linear subsystems were synthesized under the help of lineal closed-loop controllers. The simulation test results show that independent control on two degrees of freedom of radial position for the bearingless induction motor can be realized through NNIS method and the dynamic and static performance of the closed loop system designed is satisfactory.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123394853","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}

It can be classified into two types according different current detection method. One is the load current detection type, and the other is the source current detection type. Load current detection method is an open-loop system, so both time delay and parameter deviation of the PAPF (especially in harmonic detector of PAPF) can cause incorrect compensation and unwanted remaining harmonics in the source current. Source current detection is a closed-loop system, while in traditional source current detection control method, system stability and performance of harmonic elimination is incompatible. In this paper a novel source current detection control of PAPF with selective harmonic compensation is proposed. Implementation of the proposed method in either synchronous or stationary frame is given in this paper. This method can ensure both the excellent performance of PAPF and the system stability. Moreover, this control method is insensitive to time delay and parameter deviation of the PAPF. Finally, simulation and experiment results are presented to demonstrate the conclusions.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122131404","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}

Hoshi, Syoichi Nagata","doi":"10.1109/IPEMC.2009.5157626","DOIUrl":"https://doi.org/10.1109/IPEMC.2009.5157626","url":null,"abstract":"Auxiliary resonant snubber inverters (RSIs) have been proposed a solution of demands for inverter, which are high efficiency and low EMI. In RSI, zero voltage switching (ZVS) on the inverter main switches is achieved by use of the auxiliary circuit; however, additional conduction loss increases simultaneously. The operating frequency of the auxiliary circuit in RSI can be reduced to a half of switching transition of a main switch when natural ZVS, in which ZVS can be achieved without using auxiliary circuit by using output current, is used. As a result, additional conduction loss can be suppressed. However, in this scheme, ZVS turn-on on main switch is failed near zero output current when dead-time was constant. As a solution for this problem, adjustable dead-time control scheme for RSI has been proposed; however, output current is distorted in low output power range. Thus, this paper proposes a dead-time compensation scheme for adjustable dead-time control. This paper shows the basic concept of the proposed compensation scheme. In addition, the effectiveness of the proposed scheme was verified through simulations using PSIM and experiments. As a result, it was verified that the proposed control scheme was able to improve THD without decreasing in efficiency.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124679275","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}
