本文利用MATLAB的遗传算法工具箱，对弦长和扭角沿风力机展向分布进行优化，得到设计工况下的最优叶片设计。目标函数是设计工况下基于动量叶素理论和Glauert等修正所得出的功率系数。在设计工况下得到的设计结果，其功率系数在一定的风速范围内都能保持一个较高的数值，同时其有效攻角分布大致都在所选翼型的升力与阻力系数的比值最大处，与理论相符合。其结果说明该优化实际的有效性。(In this paper, the use of MATLAB genetic algorithm toolbox, chord length and twist angle along the wind turbine development to distribution optimized to obtain the optimal design conditions blade design. The objective function is to design conditions based on the results of momentum blade element theory and Glauert correction power factor. Design results in the design conditions, the power factor within the range of wind speeds can maintain a higher value, the effective angle of attack distribution substantially in the the selected airfoil lift and drag coefficient ratio of maximum , theoretical analysis and show. The results indicate the validity of the actual optimization.)

利用kalman滤波算法对状态空间描述的位移测量系统进行了滤波处理，对系统输出的真实位移、测量位移和滤波位移进行了对比，显示了kalman滤波算法较好的滤波性能。(Displacement measurement system described by the equation of states were filtered by Kalman filter algorithm. The output of the system, including the real displacement, measuring displacement and filtering displacement were compared, and the results showed the great performance of Kalman filter algorithm.)

说明：  这个MUSIC算法好像有点问题，望大家帮忙(the MUSIC algorithm appears to be a problem, we hope to see help)
