A PI controller for the single-phase grid-connected photovoltaic system has been proposed in this simulation. the proposed system consists of maximum power point tracker (MPPT) controller and PI current controller only. The proposed MPPT controller generates current reference directly the solar array power information and the current controller uses PI technique for the tight regulation of current

说明：  一个功率谱估计的程序，有需要的可以研究一下(A power spectrum estimation program can be studied if necessary.)

说明：  充分利用估计误差的比例,积分,微分信号考虑一类线性系统的参数化观测器设计问题,在加快观测器收敛速度的同时避免较大的超调.从理论上分析此类观测器设计的可行性,并从实际应用角度给出一种简单可行的参数设计方法.仿真实验表明:该观测器不但易于实现而且能够获得较好的估计效果,从而有利于在实际工程中的应用.(In this paper, the proportional, integral and differential signals of the estimation errors are fully utilized to consider the design of the parameterized observer for a class of linear systems. The convergence speed of the observer is accelerated and the overshoot is avoided. The feasibility of the design of the observer is analyzed theoretically, A simple and feasible parameter design method is given from the point of view of practical application. Simulation results show that the observer is not only easy to implement, but also can obtain good estimation effect, which is conducive to the application in practical engineering)

matlab code for qpsk modulation technique

据说是耶鲁大学的图像处理matlab文件，请大家参考。。。貌似挺高级的(Yale University said image processing matlab file, please refer to. . . Looks like a very advanced)

这是我们学Matlab的课件，通俗易懂，希望大家可以看看，非常有用！(This is our study of the Matlab software, user-friendly, I hope that we can see, very useful!)

对GpS信号的产生，捕获或跟踪都进行matlab仿真，源代码，希望帮助大家(On GpS signal generation, capture or track all to matlab simulation, source code, want to help you)
