用两点法辨识一阶惯性滞后系统，测试结果比例系数和时间常数辨识结果较准确，但输入延迟时间差距较大，分析其原因，可能是因为在曲线上取的两点坐标不准确，因为离散的数字量坐标取值方法有误。(Two points )

扩展卡尔曼、无迹卡尔曼滤波、粒子滤波的算法对比，可以参考参考(Extended kalman, no trace kalman filter, the particle filter algorithm of contrast, hope that it help you.)

说明：  老外的电机学教材，最为重要的是有相应的MAtlab代码，每一章都有，十分详细，学习电机的必备工具书，文件是在太大，此处上传chap2的源码(Foreigners motor learning materials, the most important thing is there is a corresponding MAtlab code, each chapter has a very detailed study of the motor necessary books, documents are too large to upload here chap2 source)
