PID控制，可以实现延迟控制与Dalin算法。(PID control can be achieved the delay control Dalin algorithm.)

This program is written to compute the position and angles roll-pitch and yaw through navigation system of Local-Level- coordinate system.

本书既包含了数字信号处理的经典内容，也包含了部分前言内容。理论与应用相结合，特别注重应用matlab来解决理论与算法的实现问题，对于数字信号处理的学习者很实用。  (The book contains both the digital signal processing classic content, but also contains some foreword content. The combination of theory and application, with particular emphasis on applications to solve matlab realization theory and algorithms for digital signal processing learners very practical.)

自编小波变换程序，小波基Morlet，matlab环境。(Self wavelet transform process, wavelet Morlet, matlab environment.)
