The cogging torque map carried out from these methods is then used in a Field Oriented Control (FOC) algorithm to mitigate the ripple in speed and torque. The first method uses a high bandwidth position control loop in a FOC structure, in which a slow and accurate positioning of the rotor is implemented and the cogging torque map is extracted from the q-axis current. Second method uses Load Torque Observer (LTO), which is able to observe various disturbances like load, friction but also the cogging torque. These two methods are experimentally verified and compared. After having identified the most significant harmonics in the cogging torque waveform, they have been suitably added to the q-axis current reference of a FOC in order to mitigate the ripple in torque and speed caused by cogging torque. The effectiveness of the cogging torque reduction algorithm was experimentally verified by significant minimization of the speed ripple.","PeriodicalId":353978,"journal":{"name":"2019 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122050337","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}

As an important part of the estimator design, an observability study is provided for the nonlinear model and an observability condition is formulated as well. The estimators are compared experimentally around zero stator frequency with respect to the speed estimation performance.

The controller is based on the non-linear two-track model of the vehicle and TMEasy tire model with neglected load transfer. The model is linearized along the trajectory over the prediction horizon. The steering angle is provided by the driver while the model predictive controller (MPC) calculates the optimal torques on each wheel. In order to test if the controller improves reference tracking while fulfilling given constraints, tests using the sine with dwell maneuver are performed and the results are compared to an MPC with linear tire model and to the passive vehicle behavior.","PeriodicalId":353978,"journal":{"name":"2019 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134151913","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}

The faults mainly include stator inter-turn short circuit, open and short circuit in the rectifier and open and short circuit in the stator wires. Until present, a lot work has been done to detect and localize stator inter-turn faults (which is the most critical of all the electrical faults), but not much work has been done for the detection and localization of other four electrical faults. Therefore, this paper mainly focuses on the detection and localization of the other four faults. The paper attempts to identify fault signatures in the frequency spectrum that correspond to each of these faults by using the rectified output voltage (measured experimentally) from the generator output. After the identification of these fault signatures, approaches are developed for the detection of faults along with their severity and localization. Two approaches, bandpass filter approach and harmonic magnitude computation using Goertzel algorithm are presented. Both these approaches are able to detect the four electrical faults. With the band-pass filter approach, fault severity can be determined but fault cannot be localized, but with the second approach of harmonic magnitude computation using Goertzel algorithm the fault can be localized. Both of these approaches are applicable over a wide speed range and their effectiveness of electrical fault detection is shown in this paper.","PeriodicalId":353978,"journal":{"name":"2019 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115204912","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}

The proposed alternatives are synchronous reluctance machines (SyRM) and its derivatives, assisted synchronous reluctance (PMASR) machines. These solutions rely on high reluctance torque thus theoretically needing no magnet material in the rotor structure. This paper covers reluctance machine theoretical background, rotor parametrization, design alternatives, structural analysis, and optimization. Commercially available traction reluctance machines applications have been investigated. Marine and freight traction and commercial vehicle power take-off have been selected as application niches. Finally, a performance comparison for different saliency ratios of the ideal SyRM, ferrite and neodymium PMASR has been conducted.","PeriodicalId":353978,"journal":{"name":"2019 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124116816","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}

A machining robot can perform any type of movement in space, the working space is relatively large and can be even extended based on a linear track (7th axis of the robot). Robotic milling is also a flexible and easily reconfigurable system and compared to conventional CNC machines, it is also a cost-saving alternative. However, there is still one main limitation concerned with a lower absolute robot accuracy, in comparison with CNC machines, caused mainly by a lower stiffness of the robot's serial kinematics and/or a backlash error resulting from robot's drives reversion. In this paper, we mostly present experimental results (milling) in order to demonstrate real limitations of robotic machining based on a Leica Laser Tracker system and a measuring arm CimCore. There is also described an approach for online robot path compensation based on the Laser Tracker absolute measurements in real-time where we reached the accuracy of finished products to be from tenths of mm to hundreds of mm.","PeriodicalId":353978,"journal":{"name":"2019 International Conference on Electrical Drives & Power Electronics (EDPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128882340","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 case of fault operation the space vector differs from the ideal shape (circle or hexagon). An efficient pattern recognition requires the filtered and unfiltered output voltage. The space vectors for different failure types (unsymmetrical phases, missing modulation signal, short-circuited or permanently switched off IGBT) can be simulated and stored. By comparison with the measured space vector a pattern recognition algorithm locates the failure very fast and precisely. This method could save a lot of time for the frequency inverter manufacturer.
