The main result of our proposed control scheme is that a linear time-varying controller results from the consideration of the exact tracking error dynamics and static passive output feedback controller design. The measuring of the angular velocity is not really necessary and the control law is synthesized using only a linear time-varying combination of the converter current and voltage variables. The voltage reference trajectory for the converter is generated exploiting a partial differential flatness property of the combined system. The reference trajectories of the average control and the input current are calculated via stored energy considerations and planning for the initial and final stationary regimes. The discrete switching control realization of the designed continuous feedback control law is accomplished by means of a traditional PWM-modulation scheme.

However, the surveys are aimed at establishing a classification of the topologies reported, and do not explicitly take into account the reliability. This paper presents a reliability-oriented survey of the inverter topologies reported in the literature. The survey is aimed at finding out how well the designers have solved the reliability issue. As such, it complements previous surveys focused at issues such as maturity of the technology. Also a reliability prediction of four photovoltaic systems is presented: a two-stages system, a three-stages one, and two integrated topologies, one with a boost-inverter, and the second with a buck-boost inverter. The goal is to identify the most failure prone components, and the stress factors with the highest contribution to the failure rate. In all cases, it was found that the transistors are the most vulnerable components, and that the dominant stress factor is related to the temperature. It was also found that the reliability can be improved if the switching devices are overrated, but only to a certain level, and using too large transistors can be counterproductive","PeriodicalId":131301,"journal":{"name":"2006 IEEE International Power Electronics Congress","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115332928","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}

This kind of system has already been considered in the past by other researchers, mainly by using PI-type regulators. However, it must be reminded that in electrical machines the existence of parameter changes (caused by several reasons like winding temperature variation, hysteresis and saturation, amongst others) is well recognized, but rarely accounted for. For this reason, a non-linear control strategy, namely SMC, has been considered. SMC has various attractive features like order reduction, robustness, disturbance rejection, and, sometimes, simple implementation. In this paper, some ideas of SMC applied by Utkin et. al. for controlling the speed or torque of a squirrel-cage induction motor are used to design a controller for regulating amplitude and frequency of the voltage generated by a DFIG, which is a wound-rotor induction generator. First simulation results are presented as well. Finally, the conclusions of the work are given and future activities are described","PeriodicalId":131301,"journal":{"name":"2006 IEEE International Power Electronics Congress","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124338693","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 sensorless control techniques require of the estimation of internal state variables of the machine like the linkage fluxes and the rotor speed. Generally, the estimation of the rotor speed is achieved through only the measurement of voltages and currents. Robustness of the open loop speed estimators is poor due the parametric variation therefore, to improve the robustness against the parameters and signal noise, the researches employ closed loop observers for the estimation of the state variables as well as the on-line identification of the motor parameters. However, it is well know in the literature on sensorless control that operating the motor at low frequency is challenging and that the design for such case will have to exploit parasitic effects of the machine, that furnish additional information on the state of the motor, like the rotor slot harmonic voltages. This paper presents a digest of some solutions recently reported to improve the performance in the speed estimation and some results about the observability of the induction motor in sensorless conditions","PeriodicalId":131301,"journal":{"name":"2006 IEEE International Power Electronics Congress","volume":"527 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124886312","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}
