Purpose: This contribution analyzes which performance measurement methods are used in industrial practice. The focus lies on methods used for the evaluation of investments (such as efficiency improvement programs) in engineering departments. Approach: The contribution is based on an empirical study. 56 persons working in project business were asked via a web-based questionnaire. Findings: Although the meaningfulness of holistic performance measurement is undisputed, traditional non-holistic methods prevail in industrial practice. Most engineering organizations use cost-oriented methods which do not consider the influence of engineering in the company in an adequate way. However, holistic and multi-dimensional approaches for performance measurement in engineering have gained a foothold in industrial practice. Originality: Performance measurement in engineering has been topic of very few publications yet, while studies focusing on R&D departments are numerous. Since R&D and engineering functions share some characteristics, research on R&D is also considered in this contribution.","PeriodicalId":240337,"journal":{"name":"2014 IEEE International Conference on Industrial Technology (ICIT)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115639940","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}

For the control of cell capacitor voltage of each cell, it is necessary to know the state of the voltage and it is generally measured by voltage sensors. And, to sample the voltage of each cell at every sampling instant, the associated measurement and communication hardware and signal processing time would be prohibitive as the number of cells in each arm of MMC for HVDC application is above several hundreds.

For the conventional 12/14 BLSRM, there is only a small conduction range for positive torque generation. In order to solve this problem, shifting stator pole technology is applied in the proposed structure. It is good for increasing the output torque and simplifying the control circuit. However, the proposed motor becomes a two-phase motor. As a result, the motor can't realize self-starting at some rotor positions due to torque dead point or dead zone. Therefore, in this paper, self-starting analysis of the proposed motor is firstly analyzed. A step-airgap starting method is applied to implement self-starting at all rotor positions. Furthermore, the effect of starting method on the motor performance such as torque and suspending force is also investigated by means of finite element analysis (FEA). Finally, surface response method and genetic algorithm are employed to optimize structure parameter to improve the motor performance.","PeriodicalId":240337,"journal":{"name":"2014 IEEE International Conference on Industrial Technology (ICIT)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125425494","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}
