代码说明：

matlab仿真程序，产生QPSK调制的信号，严格按照QPSK的调制步骤分I路Q路产生信号，最后两路相加，产生已调信号，调制信号随机产生，载波信号是余弦信号。(matlab simulation program to produce the QPSK modulation signal, in strict accordance with the QPSK modulation of the sub-step road Q road I have a signal, the sum of the last two, have been transferred signal, randomly generated modulated signal, carrier signal is a cosine signal.)

MATLAB模型，双馈风电机组基于最大功率跟踪，低风速超速控制，中风速高风速变桨距控制(DFIG MATLABThe wind turbine and the doubly-fed induction generator (WTDFIG) are shown in the figure called The Wind Turbine and the Doubly-Fed Induction Generator System. The AC/DC/AC converter is divided into two components: the rotor-side converter (Crotor) and the grid-side converter (Cgrid). Crotor and Cgrid are Voltage-Sourced Converters that use forced-commutated power electronic devices (IGBTs) to synthesize an AC voltage from a DC voltage source. A capacitor connected on the DC side acts as the DC voltage source. A coupling inductor L is used to connect Cgrid to the grid. The three-phase rotor winding is connected to Crotor by slip rings and brushes and the three-phase stator winding is directly connected to the grid. The power captured by the wind turbine is converted into electrical power by the induction generator and it is transmitted to the grid by the stator and the rotor windings.)

“模拟退火”算法是源于对热力学中退火过程的模拟，在某一给定初温下，通过缓慢下降温度参数，使算法能够在多项式时间内给出一个近似最优解。退火与冶金学上的‘退火’相似，而与冶金学的淬火有很大区别，前者是温度缓慢下降，后者是温度迅速下降。(Simulated Annealing)
