The generating systems use Doubly-Fed Induction Generators (DFIGs) to achieve high
conversion efficiency and to reduce the installation cost. This paper presents a modeling and Maximum
Power Point Tracking (MPPT) control method of DFIG-based variable-speed wind energy conversion
system. The generator considered is a wound rotor induction machine whose stator is connected directly
to the grid and the rotor is fed through back-to-back Pulse-Width Modulation (PWM) converters. Stator
flux-oriented vector control is applied to control the active and reactive current loops independently. The
MPPT control method in a Wind Energy Conversion System (WECS) is proposed. The proposed control
solution aims at driving the position of the operating point near to optimality. This is a very important
aspect to maintain DFIGs efficiently in a variable wind speed. The wind generator is modeled in RSCAD
program which is interfaced with the Real Time Digital Simulator (RTDS).

adaboost_version1e
这是一个经典的形变模型实施,在一个单一的文件用简单的可以理解的代码。
功能包括两部分一个简单的弱分类器和一个促进部分:
弱分类器试图找到最佳阈值的数据维数对数据进行分离成两个阶级1和1
要求的进一步提高分类器部分迭代,每一步是变化分类权重miss-classified例子。这造成了一连串的“弱分类器”,表现得像一个“强大分类器”
(This a classic AdaBoost implementation, in one single file with easy understandable code.
The function consist of two parts a simple weak classifier and a boosting part:
The weak classifier tries to find the best threshold in one of the data dimensions to separate the data into two classes-1 and 1
The boosting part calls the classifier iteratively, after every classification step it changes the weights of miss-classified examples. This creates a cascade of "weak classifiers" which behaves like a "strong classifier"
