产生QPSK信号，根据仿真的数据估计差错概率(Produce QPSK signal and estimate the data according to the error probability)

说明：  利用matlab的GUI编程完成了用于解决二维多类问题的分类器算法，并实现了方便的人机界面（在matlab2008a环境下编写的，由于matlab界面生成工具GUIDE版本上可能存在不兼容性，在其他低版本的matlab中运行时可能会发生错误）(GUI programming using matlab s done to resolve the problem of two-dimensional multi-class classification algorithm, and implemented to facilitate man-machine interface (written in matlab2008a environment, due to interface generation tool matlab GUIDE version of the incompatibilities that may exist, In other lower version of matlab in the run-time errors may occur))

MATLAB构建的三段比幅式距离保护模型 内涵保护模块 S函数模块 (MATLAB built three-spoke distance protection model content protection module S function modules)

常规PID控制器主要采用模拟PID控制器。这种控制器的控制规律是：根据给定值和输出值构成的偏差按比例、积分和微分通过线性组合构成控制量，对被控对象进行控制。(Conventional PID controller is used mainly analog PID controller. This controller is the control law: according to the given value and output value constitutes a deviation by proportional, integral and differential form by a linear combination of the amount of control, control of the controlled object.)
