In the FDFOC, a fuzzy logic adaptation mechanism based Luenberger observer used for speed adaptation is adopted, and all the proportional-integral (PI) controllers are substituted for intelligent ones: fuzzy logic controllers (FLCs). In the interest of evaluating both systems performance FDFOC and DFOC, a detailed comparative study is presented: functioning in both motor rotation directions with application of load torque disturbance at low speeds. Simulation tests prove the robustness of the new infrastructure FDFOC in comparison with the usual DFOC: Quick response, good load torque rejection, decrease of the stator phase current on startup, as a result the system dynamic has been improved significantly. On the other hand, the simulation presents excellent speed observation using adaptive Luenberger observer (ALO) whereas the estimated speed perfectly pursues the reference at low speeds. Simulations are done using Matlab.","PeriodicalId":345854,"journal":{"name":"2016 5th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115412183","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 development of low drop-out (LDO) regulator architectures in the power management family is necessary to reduce the standby power of portable applications such as cellular phones and PDAs. In essence, this LDO regulator suffers from an inherent load regulation which impedes to work under various applications. Indeed, this paper discusses a technique that enables the practical realizations of high Load regulation LDO's at low voltages. The objective of this research is to develop novel LDO regulators that can achieve a high precision of LDO which requires a high loop gain performance. Moreover, one of the performances which is enhanced by the augmentation of dc open loop gain is the load regulation. The LDO is implemented in 90 nm CMOS technology and achieves a power-supply rejection ratio better than −70 dB up to 100 KHz for load currents up to 100 mA. The voltage regulator provides maximum 110 mA current, moreover with a 1.2V supply voltage, thus this LDO regulator providing an output of 1 V with a 200mV drop-out voltage.","PeriodicalId":345854,"journal":{"name":"2016 5th International Conference on Multimedia Computing and Systems (ICMCS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115015527","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}
