Whereas blind people largely use feeling in everyday life, sighted person mainly focus on hearing and vision. However, haptic interface started being introduced in customers applications, such as smartphone, to propose new opportunities to users. A surface put in vibration nearby another can modify the friction coefficient measured between the two objects. This is known as the squeeze film effect. The aim of this paper is to present the optimization of a piezoelectric actuator for friction feedback. Since the computation of the Squeeze film Finite Element (FE) model is time-consuming, it is also proposed to focus only on the mechanical simulations. Indeed, a correlation between the force of the actuator and the volume swept by the travel of the vibrating surface is brought out. Finally, a couple of optimization results are presented for different topologies of actuators.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121532186","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}

Electric machine types and power ratings, in addition to battery types and energy storage capacity are surveyed. A large database is then constructed and analyzed. Trends are shown to correlate well with global events and major automotive milestones with the rise and fall of different technologies. Three time periods are addressed between the first the automobile production and 2013. Future trends and expectations are then built based upon previous trends.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128939516","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}

Typically, a simulation of the electrical machine behavior and its control is either time consuming or inaccurate. This paper presents a magnetic switched reluctance machine (SRM) model considering material saturation, mutual coupling, asymmetries in excitation and possible asymmetries in geometry. The machine model enables a dynamic motor simulation in combination with control and inverter. This is necessary when considering operation of special fault tolerant SRMs. Furthermore, the unbalanced stator- and rotor tooth forces due to asymmetric excitation during fault operation are calculated. The model can be used with distributed inverters and their respective control structures to effectively design suitable fault tolerant control strategies.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130715854","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}

Predictive control algorithm can achieve fast dynamic response while avoiding overshoot. However, there is an inherent defect that it relies on the accurate mathematical model of the controlled object.

The relationship between system stability and parameter mismatch was analyzed using root locus method. Simulation and experimental results demonstrate that the proposed incremental predictive current control algorithm shows well dynamic performance and the improved updating strategy achieves significantly increased robustness to parameter mismatch, verifying the feasibility of the methods presented.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131682133","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}
