Starting from the basic rectangular variation, the ascending and descending flanks of the function are modeled using a cosine, exponential and a more general approach (further referred to as piecewise cubic sharing function). The degrees of freedom varying between two and an arbitrary number (for the general approach) are determined so as to minimize losses, when operating in smooth torque conditions. Based upon an optimisation procedure with both linear and nonlinear constraints, the total (copper and iron) losses are minimized considering a limited available DC bus voltage. Moreover, a smooth model is presented so as to be able to separate the two main causes for the torque ripple and it is shown that, neglecting the chopping ripple, a ripple-free torque can be obtained. Extensive studies have been conducted for determining the optimal number of degrees of freedom (DoFs) for the piecewise cubic function. The proposed methods were successfully implemented on a 8/6, 30kW peak power, SRM both numerically and experimentally-wise.","PeriodicalId":382406,"journal":{"name":"2012 13th International Conference on Optimization of Electrical and Electronic Equipment (OPTIM)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127085700","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 benefits which can be achieved by using the new system are: reduction the amount of some pollutants such as unburned hydrocarbons from the exhaust gases, improving the engine's efficiency, fuel consumption decreasing and also some unwanted engine processes (misfires, hesitations, detonations, stutters and stumbles) can be avoided. The first phase of the validation process of the new ignition system was to perform a diagnosis of the plasma produced using the new spark plug and to compare the results with the ones obtained from the diagnosis of the plasma produced by a classical spark plug. Also the electrical parameters were measured for both the spark plugs and for different waveforms of the control signals. In this paper we present a correlation between the rotational temperatures of the plasma and the energy consumed by the discharges produced using the classical and the double spark plugs. The spectra used to determine the rotational temperatures have been recorded in air at atmospheric pressure using a spectrometer equipped with a CCD camera. The electrical discharge voltage and current measurement used to calculate the energy of the discharge have been made in air using a high voltage probe and a shunt resistance.","PeriodicalId":382406,"journal":{"name":"2012 13th International Conference on Optimization of Electrical and Electronic Equipment (OPTIM)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125058935","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}

Both neural networks and fuzzy systems perform nonlinear mapping and both systems internally operate within a limited signal range between zero and one. Neural networks can handle basically an unlimited number of inputs and outputs while fuzzy systems have one output and number of inputs is practically limited to 2 or 3. The resulted nonlinear function produced by neural networks is smooth while functions produced by fuzzy systems are relatively rough. At the same time the design of fuzzy systems transparent and easy to follow while the development of neural networks is much more labor intensive. It is shows that most commonly used neural network architecture of MLP - Multi Layer Perceptron is also one of the least efficient ones. Also most commonly used EBP - Error Back Propagation algorithm is not only very slow, but also it is not able to find solutions for optimal neural network architectures. EBP can solve problems only when large number of neurons is used, but this way neural network loses its generalization property. Performances of both fuzzy systems and neural networks are compared leading to the conclusion that neural networks can produce much more accurate nonlinear mapping and they may require less hardware.","PeriodicalId":382406,"journal":{"name":"2012 13th International Conference on Optimization of Electrical and Electronic Equipment (OPTIM)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122361932","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}

On the other hand, the general trend of reducing the dimensions of the integrated structures one inherently leads to the increase of their structural parasitic effects. Therefore, the minimization of the parasitic capacitances and inductances represents an important issue for increasing the performances of a magnetic integrated structure. In this light, the paper proposes a method for the minimization of the equivalent parallel capacitance (EPC) of these structures based on optimal design. The paper describes the optimization algorithm developed by the authors designed to determine the optimal placement of the structure's conductor routes that minimize the structural inter-winding capacitance. In the first part of the paper the theoretical background is presented while in the second part the optimization algorithm validation and numerical examples are outlined, followed by the final conclusions.","PeriodicalId":382406,"journal":{"name":"2012 13th International Conference on Optimization of Electrical and Electronic Equipment (OPTIM)","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122524671","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}
