改进的微分先行PID控制算法仿真源程序。 适用于输入信号跳变剧烈的场合，避免骤升或骤降时引起的系统震荡。(Improved differential forward PID control algorithm simulation source. Applied to the input signal transitions dramatic occasions, to avoid swells or sags caused when the system oscillation.)

matlab用来解一般线性或者非线性方程的方法及应用公式。(matlab used to solve a general linear or nonlinear equations and application of formulas.)

本代码的方法是借助旋转不变技术估计信号参数(Estimation of Signal Parameters via Rotational Invariance Techniques)，现已成为谐波恢复（即正弦波个数及频率估计）的一种主要特征分解法。(This code is to help the estimated ESPRIT signal parameters (Estimation of Signal Parameters via Rotational Invariance Techniques), has now become the harmonic retrieval (that is, the number and frequency sine wave estimated) of one of the main characteristics of decomposition.)

顺序表（即向量类），包含创建，插入，删除，查找等功能。(The order of the table (ie vector class), including creation, insert, delete, search and other functions.)

说明：  NCO模块的设计函数，用于产生正弦、余弦信号(It s a design functions about NCO module ，which is used for generating sine, cosine signal)

基于matlab的MUSIC及解相干MUSIC算法(MUSIC MUSIC and coherent solution algorithm based on the matlab)
