Since for such drives the excitation is created by the magnetizing current which is part of the stator current along with the torque generating fraction, there are two degrees of freedom in the stator current generation to achieve a certain amount of torque. As for high integrated drives maximum efficiency is essential to reduce inverter heating to a minimum there arises the condition of a minimal stator current magnitude to torque ratio. The following article comprises a recipe for an analytical approach to an efficient induction machine stator current control. Influences of a saturated mutual inductance are taken into account to elaborate characteristic curves of magnetizing current versus torque to ensure minimal thermal stress on the inverter and thus compact design for induction machine servo drives especially applied for battery applications.","PeriodicalId":162453,"journal":{"name":"2011 IEEE International Symposium on Industrial Electronics","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115917200","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 impact of unbalances in power demand (load) and renewable power injection on the power quality is relatively small due to the also small output impedance of the rotating generators. However, when a battery inverter is required to form the grid, the power quality can deteriorate significantly in the presence of unbalanced power injection/demand in the system, due to the larger impedance of the low-pass output filter. The conventional approach of using three-phase dq control and symmetrical components decomposition (SCD) usually results in slow dynamic response. This paper proposes a per-phase dq technique that does away with the need for SCD and presents superior dynamic performance as demonstrated by simulation.","PeriodicalId":162453,"journal":{"name":"2011 IEEE International Symposium on Industrial Electronics","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123908697","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}

Traditional drive methods for induction machines such as vector control usually require complex control routines, fast processing unit and multiple system status feedbacks. The complexity of these methods greatly reduces the reliability of the system since the failure of the sensor or even the drift of system parameters could potentially result in system malfunction. This creates the need for a simple, cost-effective and reliable control strategy as a backup to continue operation of the system in case of failure of current and voltage feedback sensors. In this paper, an effective, yet simple and low-cost state switching control technique is proposed and implemented for a three phase squirrel cage induction machine system. This state switching control operates at two specific duty cycles of PWM which produces phase voltages with different magnitudes across the phase windings. At the same time, the frequency of phase voltages is derived from the reference speed. By switching between these two states, precise speed regulation can be achieved. This new control method makes the controller extremely simple in design and implementation for induction machine. Simulation and experimental results are included in this paper to validate our claims.","PeriodicalId":162453,"journal":{"name":"2011 IEEE International Symposium on Industrial Electronics","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116990764","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 compensator consists of VSI and an LC filter for smoothing VSI output voltage. Presence of the filter makes control of the compensator more difficult due to dynamics of a second order plant introduced by the filter which results in oscillations during a sudden voltage change. Multiloop controller is able to compensate the effect, however measurement of additional signals is needed.
