They have very large potential in future industrial applications. Sliding mode control is an effective control method for these converters due to their nonlinear property. Previous work has solved the problem of constant switching frequency. But those controllers cannot alleviate the steady-state error. In this paper, an improved sliding mode controller is proposed. With a double integral term, it can eliminate the steady-state error despite of the input disturbance and load variation. Simulation and experimental results are provided for verification of our design.","PeriodicalId":160078,"journal":{"name":"2009 35th Annual Conference of IEEE Industrial Electronics","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126554208","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 paper, the recently presented selective harmonic mitigation technique (SHMPWM) is adapted to a nine-level converter. Its flexibility is exploited to meet the EN 50160 and CIGRE WG 36−05 grid codes without any additional filtering system using 10 switching angles per quarter of period in a wide range of amplitudes of the fundamental harmonic from 0.70 to 1.22. Some results validating this technique applied to this topology are presented.

The response of a fuel cell system depends on the air and hydrogen feed, flow and pressure regulation, and, heat and water management. In this paper, the study is concentrated on the air subsystem that feeds the fuel cell cathode with oxygen. An IP control, a RST regulator and a higher order sliding mode control, super-twisting algorithm, with variable gains, have been designed and validated experimentally to control the air flow of the moto-compressor system, composed of a DC motor driving a volumetric compressor of type piston, designed to feed a 500W fuel cell with air. Experimental results show better performance with the sliding mode control, especially when dealing with a delayed air flow sensor response.","PeriodicalId":160078,"journal":{"name":"2009 35th Annual Conference of IEEE Industrial Electronics","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125618405","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}

Therefore high traction forces have to be transmitted on a small area. As a result, the conveyor is charged with strong mechanical stress. In order to increase the durability of the conveyor, it seems to be benefiting to drive the conveyor directly by a linear motor. Another estimated advantage of this approach is to get a more dynamic drive which could also be very compact. It is also possible to arrange a number of linear drives along the conveyor, in order to achieve the desired feeding forces and to reduce tension forces. The following article presents a designing guide for a linear motor in this application. Thereby the geometrical dimensions and the design of the winding stand in the foreground.","PeriodicalId":160078,"journal":{"name":"2009 35th Annual Conference of IEEE Industrial Electronics","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125630505","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}

Signals encountered in rotary machine systems can be broadly classified as being either stationary or nonstationary. This study evaluates the performance of the traditional method-polynomial fit filtering with Fourier spectrum analysis and the new developed method-empirical mode decomposition with Hilbert transform (EMD+HT), in mechanical signal decomposition. The former method is based on the sense of least squares, thus insensitive to noise. However, it demands a predetermined time scale, which is unchangeable once fixed, while EMD is adaptive with multi-resolution and univocal. One shortcoming of the latter approach-sensitive to noise, is alleviated by the wavelet threshold de-noising method. A synthetic signal as well as a path error signal of precision working table is analyzed using the two methods. Evaluation is made upon the mode mixing phenomenon and illusive components problem included in EMD with proposed indicators, which confirms the validity of this method used in mechanical signal decomposition.","PeriodicalId":160078,"journal":{"name":"2009 35th Annual Conference of IEEE Industrial Electronics","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125669256","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}
