Development of Fuzzy Inference Scheme for LC Oscillator Design

Oscillators are an artefact of Electrical Technology. By and large oscillator designing can be viewed as a ‘Scientific Art’. Furthermore, the use of computer in the designing process of oscillator added the wings to it. FuzzyLogic-Computer-Aided-Design (FLCAD) using MATLAB FUZZY TOOLBOX amalgamates the ability of Fuzzy Logic to model colloquial propositions involved in the oscillator design. Designing even simplest of oscillator that is efficient and economical is a multi-fold process that runs through great deal of numerical manipulation. This is the intention to go for the development of tool-box type Fuzzy based CAD for oscillator designing. Fuzzy Logic is mainly exploited to make the trade-off decisions over numerical data and conflicting issues raised by conventional design techniques. For modelling of LC oscillator TSK method is used. The TSK method uses linear equations for consequences part. The ANFIS tool from fuzzy toolbox automatically generates such kind of linear equation by using numerical MATFILE data. The use of FIS has been extended to design of LC oscillators. Keywords— Oscillator, Design Algorithm, Fuzzy Logic, Fuzzy Reasoning, TSK modelling
