This article presents a new fuzzy inference engine for the problem of fusing identity information coming from dissimilar sources. The most popular fuzzy systems in engineering, i.e. the product and the minimum engines are studied and compared to a new model, derived from Bayesian statistics. Several simulations are done to evaluate engines performance under(More)
This paper presents a new wind speed sensorless maximum power point tracking (MPPT) controller for variable speed wind energy conversion systems (WECS). The MPPT control of the WECS, in this work, is achieved using optimum speed - power curve of the WECS after taking into account the changes in system efficiency while operating at different operating points(More)
