The use of speed sensors (encoders) for speed control introduces difficulties in drives operation and degrades the reliability especially in hostile environments, and makes the system more expensive to maintain and replace. This increases the demand for speed sensor-less induction motor drive schemes where the speed is estimated through various estimation schemes and algorithms. One such method of speed estimation is through the estimation of stator flux of the machine. But the major drawback of this method is its dependence on stator resistance for flux estimation; the stator resistance of an induction motor varies with operating conditions such as loading and temperature. An improved stator flux estimation technique with online stator resistance estimation is proposed in this paper. Stator flux estimator discussed in the paper is based on closed loop offset compensation algorithm and the stator resistance is estimated online using the variables measured from the motor terminals. The proposed schemes for stator flux estimation and stator resistance estimation for speed sensor-less vector controlled induction motor drive are validated through extensive simulation on a Matlab-Simulink platform.","PeriodicalId":312418,"journal":{"name":"2017 IEEE Transportation Electrification Conference (ITEC-India)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129005057","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}

To boost some effective contribution towards the awareness in alternate fuels & energy, in this project, an electric All-terrain vehicle (ATV) roll cage is developed with utility factor, analyzed and validated physically with all-round performance of the vehicle. The objective of this project is development of electric All-Terrain Vehicle roll cage according to SAEINDIA rules, finite element analysis (FEA) for design validation, feasibility, safety and physical testing at event site. The roll cage is modified from one seater vehicle to three seater vehicle with luggage allowance, which is a good utility addition for an all-terrain vehicle. Transformation from gasoline vehicle to electric vehicle is also considered while development & analysis. The developed roll cage is tested under static & dynamic loading conditions. From the Finite Element Analysis and testing, the factor of safety obtained is above 2 for all cases and thus it can be inferred that the vehicle roll cage is safe, feasible and can sustain the loading environment for various cases it has been designed for and also it passes AIS Standards. This electric allterrain vehicle development will have actual utility after the event unlike regular all-terrain vehicles, as well as it will impart awareness about electric vehicles.","PeriodicalId":312418,"journal":{"name":"2017 IEEE Transportation Electrification Conference (ITEC-India)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117101013","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}

To meet this requirement, hybrid converters were introduced. But the hybrid converters have right half plane (RHP) zero in the open loop control to output DC voltage transfer function. Due to this RHP zero, the performance of hybrid converters is poor under heavy load requirements and also controller design becomes complex. In this paper, a minimum phase hybrid boost converter is proposed for smart residential uninterruptible power supply systems, which is derived from a minimum phase boost converter. The hybrid converter displays a minimum phase behavior due to the complete elimination of the RHP zero in the DC voltage transfer function. Due to the minimum phase behavior, the hybrid converter gives good dynamic performance under heavy load requirements by supplying DC and AC outputs simultaneously. Simulation results are presented to validate the steady statebehavior and dynamic behavior of proposed minimum phase hybrid boost converter.","PeriodicalId":312418,"journal":{"name":"2017 IEEE Transportation Electrification Conference (ITEC-India)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122977910","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 consists of crash sensors to detect the impact of the vehicle accident. Crash sensor activates the switch present in the high voltage battery box. The switch controls the high voltage (HV) battery main contactors and disconnects the HV battery supply. Crash zones to be defined and crash sensor to be calibrated for unintentional activation of the crash sensor. Response time should be fast enough to cut off the High voltage battery supply before the high voltage components like PDB and high voltage cable gets crushed. This paper will brief about possible collision warning with auto brake & high voltage components crash zones, vehicle safety system architecture in EV. Collision warning with auto brake, where the area in front of the vehicle is continuously monitored with the help of long-range radar and a forward-sensing wide-angle camera can fit on the cabin. In addition to monitoring front of the vehicle, system monitors 360 degree of the vehicle by using impact/crash sensor. A warning and brake support will be provided for collisions with other vehicles, both moving and stationary. Additionally, if the driver does not intervene inspite of the warning and the possible collision is judged to be unavoidable, intervention braking will be automatically applied to slow down the vehicle. The entire system will be controlled and monitored by EV controller. This aims at reducing impact speeds and thus the risk for consequences. Apart from the above safety, incase if the crash happened unavoidably, the complete HV systems will be disconnected automatically to protect the harm for the driver & passenger. EV controller monitors the high voltage, in case of any leakage, HV supply from the battery is shut down","PeriodicalId":312418,"journal":{"name":"2017 IEEE Transportation Electrification Conference (ITEC-India)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115319420","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}
