基于角谱法衍射理论的近场菲涅尔衍射的模拟(Fresnel diffraction stimulation based on angular spectral method)

对序列建立AR模型，并以概率形式给出预测数列表达。先进行平稳性检验后求取自相关函数，用Y-W法求取模型参数，并应用FPE准则确定阶数，进行预测后，给出概率表达。(AR model for the sequence established, and the probability forecast given in the form of a list. After a smooth first autocorrelation function test strike strike model parameters YW law and apply the criteria to determine the order of FPE, predict, given the probability of expression.)

这是一个matlab人脸识别程序代码，有GUI界面(This is a face recognition matlab code, there is a GUI interface)

交流位置伺服系统因其存在参数时变、负载扰动以及电机的非线性等缺点， 很难为其建立准确的模型. 模糊（ fuzzy）控制具有无需建立被控对象的数学模型、鲁棒性好等 优点，但稳态精度差. 将模糊控制和PID 控制相结合，设计了Fuzzy-PID 双模控制器. 在论域内 用不同的控制方式分段实现控制，这样就综合了模糊控制和PID 控制的优点，克服了各自的缺 点. 该控制器结构简单、易于实现. 在半闭环交流位置伺服系统上所做的实验表明，采用Fuzzy- PID 双模控制器与采用经典PID 控制器相比，阶跃响应的调整时间减少了33. 7 ，并且无超 调，轨迹跟踪误差减小了47. 2 .(AC servo system because of the presence of parameter variations, load disturbances and non-linear motors and other shortcomings, it is difficult to establish accurate models for fuzzy (fuzzy) control without having to build a mathematical model of controlled object, robustness and good However, steady-state accuracy is poor. fuzzy control and PID control are combined to design a dual-mode Fuzzy-PID controller in the sub-region to achieve control on the different control methods, so that a combination of fuzzy control and PID control advantages to overcome their disadvantages. simply the controller structure, easy to implement. experiments on semi-closed loop AC servo system did show that the Fuzzy-PID controller is compared with the classic dual-mode PID controller, step response The adjustment time is reduced by 33.7 , and no overshoot, tracking error is reduced 47.2 .)
