This paper presents a FPGA-based digital control for a DC-DC converter. The main difference from DSP-based solution is that FPGA allows simultaneous execution of all control procedures, enabling high performance and novel control methods. The control algorithm has been developed using a VHDL language or CAD state graphical approach based on the use of logical state diagram. The FPGA switching controller has been designed as simple as possible while maintaining good accuracy and dynamic response. Simulations and experimental results show the feasibility of the proposed method, opening interesting possibilities in motion and power electronics converter control.","PeriodicalId":149421,"journal":{"name":"2008 13th International Power Electronics and Motion Control Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128754623","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}

Because of the inimitability of the measured impedance curves, the method is based on the minimum error between the measured curves during operation and precommissioned reference curves. The method can handle alternating and rotating test signals. The capacity of the proposed method is tested on two different standard induction machines, which are not especially designed for sensorless control. Operation at standstill, and even at zero-frequency, is possible.","PeriodicalId":149421,"journal":{"name":"2008 13th International Power Electronics and Motion Control Conference","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115135092","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 predicted performance of the various generator options within a typical wave regime is validated by means of a time-domain MATLAB/Simulink model. The suitability or otherwise of brushed machines in the offshore marine environment is examined in detail.

We examine the effects of errors on the steady-state performance of these motors in this paper. It was found that the current amplitude increases when a parameter error is given and the effect of a back EMF parameter error is especially large. We propose a new back EMF parameter adjustment method based on these results. We determined from our simulation and experimental results that the proposed method can compensate for the current increase caused by the parameter error. A theoretical analysis showed that the proposed method is affected by only the daxis inductance parameter Ld. Therefore, even if there are errors in the other motor parameters, the motor current of the constant load condition is minimized by using the proposed method.","PeriodicalId":149421,"journal":{"name":"2008 13th International Power Electronics and Motion Control Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125820836","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 application of motors with type of protection increased safety, marked as ldquoEEx erdquo, with and without associated safety systems, are analyzed for zone 2. Risk assessment of such applications, based on the requirements of ATEX Directive, is the main part of this paper. There is a specific example which illustrates the results of selection and application of motors with type of protection ldquoEEx erdquo without the application of additional safety systems, which is the traditional approach. Possible application, in special cases, of the mentioned motor with the application of additional safety systems, which is the new approach, is also analyzed. The concept of the new approach is used in cases where diagnostic methods have determined that the basic explosion protection of an ldquoEEx erdquo motor has been undermined. To establish the actual condition of a rotor squirrel cage, a diagnostic method based on the spectrum analysis of the stator current is used. This diagnostic test can ascertain the deteriorated condition of the rotor cage which directly affects its explosion protection. Damage to the rotor cage can be a serious source of ignition of explosive atmospheres.","PeriodicalId":149421,"journal":{"name":"2008 13th International Power Electronics and Motion Control Conference","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126049662","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 adaptive speed controller uses fuzzy neural network equipped with additional option for on-line tuning its chosen parameters. In the paper PI-type and sliding-mode fuzzy logic controllers are used as the speed controllers, whose connective weights are trained on-line according to the error between the state variable of the plant and the reference model. The torsional vibrations dumping abilities of the two-mass drive system with the field oriented control of induction motor are tested and compared for both analyzed neuro-fuzzy adaptive controllers. It is shown that torsional oscillations can be successfully suppressed in the proposed control structures, using only one basic feedback from the motor speed.
