基于改进的PI模型对非线性曲线进行拟合，二次寻优算法进行参数辨识，用逆模型前馈补偿(classical PI modeling)

分析了永磁同步电机矢量控制的发展概况，然后从机电能量转换的角度出发，解释三相永磁同步电机的机电能量转换原理，推导拉格朗日运动方程。此外，列写出永磁同步电机在三相静止坐标系和dq坐标系下的数学模型。基于Simulink建立了转速电流双闭环矢量控制系统的仿真模型，通过对仿真结果分析，验证了永磁同步电机矢量控制系统性能的优越性(The development of vector control of permanent magnet synchronous motor is analyzed. Then, from the perspective of electromechanical energy conversion, the principle of electromechanical energy conversion of three-phase permanent magnet synchronous motor is explained, and the Lagrangian motion equation is derived. In addition, the mathematical model of the permanent magnet synchronous motor in the three-phase stationary coordinate system and the dq coordinate system is written. Based on Simulink, the simulation model of the speed and current double closed-loop vector control system is established. The simulation results are analyzed to verify the superiority of the performance of the permanent magnet synchronous motor vector control system.)

一款来自央视网的Flash图片轮播广告特效，支持多个Flash广告文件手动切换或自动切换，通过Txt配置文件配置后，可调用swf格式的外部广告动画文件，链接可定义在flash里，也可以通过Txt文本配置，早两年CCTV网站很常见的效果，现在貌似改版了。

点击鼠标生成随机的Flash小亮点动画，点击次数越多，亮点越多，并且亮点会自动消失，一款漂亮的鼠标动画效果。
