一种快速数字AGC结构的分析与设计，希望对大家有帮助(Structural analysis and design of a fast digital AGC)

PMSG网侧的结构包括逆变器、PWM发生器、电压矢量控制。采用电压外环和电流内环的双闭环控制。设计电流控制器时，希望稳态电流无静差，而且动态要求上，永磁直驱风力发电系统中不允许在电流调节过程中有太大的电流超调.(PMSG network side structure includes an inverter, PWM generators, voltage vector control. Using a voltage outer and inner current double closed loop control. Design current controller, hope no static error steady-state current, and the dynamic requirements, permanent magnet direct drive wind power system does not allow much of the current overshoot in the current regulation process.)

对一段语音进行端点检测并对检测的语音画出方框图，不同于一般只画竖线(Endpoint detection of a voice to draw the block diagram and detection of voice is different from the vertical line is generally drawn)

说明：  用于生成不同频段的扫频信号，以供后期开发使用(create swept-frequency signal indifferent frequency channel )

我编写的改进的elman神经网络应用程序，第一次上传(prepared by the improved elman neural network applications, the first upload)

已知指定参数值，用matlab编程实现一个滞后补偿器。已满足题目参数要求。(Known to specify parameter values, using matlab programming a lag compensator. Parameter requirements have been met subject.)
