Journal ArticleDOI
The Fourier series operational matrix of integration
TL;DR: In this article, a general expression of the Fourier operational matrix of integration P is derived which is analogous to that previously derived for other types of orthogonal functions such as Walsh, block-pulse, Laguerre, Legendre and Chebyshev.
Journal ArticleDOI
Correlation of wind speed between neighboring measuring stations
TL;DR: In this paper, a method for establishing wind speed correlation between neighboring measuring stations is presented, which takes into account the evolution of the sample cross correlation function of wind speed in time domain and uses an artificial neural network to perform the wind speed simulation.
Journal ArticleDOI
Taylor series approach to system identification, analysis and optimal control
TL;DR: In this article, the authors used the Taylor series expansion to solve the problems of system identification, analysis, and optimal control using the Walsh, the block-pulse, the Laguerre, the Legendre, Chebyshev, the Hermite and the Fourier functions.
Proceedings ArticleDOI
Behavior of a Small Four-Stroke Engine Using as Fuel Methanol - Gasoline Mixtures
Journal ArticleDOI
Analysis and optimal control of time-varying linear systems via Taylor series
TL;DR: In this paper, the Taylor series is used for the analysis of time-varying linear systems with the introduction of the product matrix of the Taylor polynomial vector and its transpose.
