自适应滤波器的应用.经过调试,最终得出的结果(滤波图象)很好,所以就上载了.(adaptive filter applications. After debugging, and ultimately the results (filter images) is very good. So on the set.)

matlab程序，用于人脸识别的，比较简单的啦，希望对比较没有基础的人有点点用(matlab procedure for face recognition, the relatively simple problem, I hope there is no basis for comparing those who have little use)

Proportional-Integral-Derivative (PID) control is the most common control algorithm used in industry and has been universally accepted in industrial control. The popularity of PID controllers can be attributed partly to their robust performance in a wide range of operating conditions and partly to their functional simplicity, which allows engineers to operate them in a simple, straightforward manner (exp. ref:national instruments). This file analyse different conditions and methods for tuning the PID controllers.
