Variational Design and Fairing of Spline Surfaces
Variational principles have become quite popular in the design of free form surfaces. Among others they are used for fairing purposes. The choice of the ‘right’ fairness functional is a crucial step. There is always a tradeoff between high quality and computational effort. I n this paper we present fairness functionals that allow fairing efficiently, i.e., produce high quality surfaces in a rea...
متن کاملUnsupervised Learning of Control Surfaces Based on B-Spline Models
Based on our earlier work on construction of fuzzy controllers with B-spline models, we propose an automatical learning approach for generating control vertices of such a type of fuzzy controller. For supervised learning, we point out that rapid convergence of this learning procedure can be guaranteed, which is confirmed by diverse examples of approximating non-linear functions and interpolatin...
متن کاملA variational approach to spline curves on surfaces
Given an m-dimensional surface Φ in R, we characterize parametric curves in Φ, which interpolate or approximate a sequence of given points p i ∈ Φ and minimize a given energy functional. As energy functionals we study familiar functionals from spline theory, which are linear combinations of L norms of certain derivatives. The characterization of the solution curves is similar to the well-known ...
متن کاملSemi-structured B-spline for blending two B-spline surfaces
Surface blending is a useful operation in geometric design for rounding sharp edges or corners. Meanwhile, NURBS has already become the de facto industrial standard in existing CAD/CAM systems. Therefore, it is required to study how to blend two B-spline surfaces. However, two arbitrary B-spline surfaces (called base surfaces) are hard to be blended with a B-spline surface (called blending surf...

در این پایان نامه، کنترل نرو-فازی در پرنده هدایت پذیر از دور (پهپاد) استفاده شده است ابتدا در روش پیشنهادی اول، کنترل کننده نرو-فازی توسط مجموعه اطلاعات یک کنترل کننده pid به صورت off-line آموزش دیده است و در روش دوم یک کنترل کننده نرو-فازی on-line مبتنی بر شناسایی سیستم توسط شبکه عصبی rbf پیشنهاد شده است. سپس کاربرد این کنترل کننده در پهپاد بررسی شده است و مقایسه ای ما بین کنترل کننده های معمو...
