matlab多年收集结果，包括程序和pdf介绍。(Matlab realized bootstrap source. )

PQ分解的程序 matlab版本 简单实用例子(PQ decomposition matlab version of the program is simple and practical example)

文中介绍了传统的PID控制原理，PID分为位置式和增量式，计算机控制是数字PID控制。一些 改进的PID控制算法是针对实际应用中的不足提出的，如积分分离式PID控制算法，抗 积分饱和算法，变速积分算法等，实际应用中，控制又分为简单PID控制和串级PID控 制，对一些典型的控制算法，选用典型控制对象用MArLAB软件进行了对应仿真。对仿 真结果进行了对比分析，说明了改进算法的作用。(This paper introduces the principle of the traditional PID control, PID into position and incremental, computer-controlled digital PID control. Some improvements in the PID control algorithm is less than the practical application of the proposed, such as discrete integral PID control algorithm, anti-integral saturation algorithm, changing integration algorithm and so on, practical application, the control is divided into a simple cascade PID control and PID control , for some typical control algorithm, selection of a typical control object MArLAB software with the corresponding simulation. The simulation results of comparative analysis carried out to illustrate the role of the improved algorithm.)

关于MATLAB的百个实用的例子，最多的是在电子方面的应用(One hundred practical examples of MATLAB, the largest in the electronics)

实现振动信号的FFT图，时域图以及两种倒谱的方法(realize the two analize way of the dao-pu for the signal)

用黄金分割法来求解函数的极小点，不用求函数的导数，只需进行迭代即可,非精确线搜索技术用于解决极值区间(Golden section method to solve the minimum point of the function, do not seek the derivative of a function, simply iteration can be inexact line search techniques for solving extremal interval)

It is matlab simulink file that contained a simple model of renewable energy system like wind solar battery. It is useful to see how the system model and how it is demenstrated as a system.

这是一个很好的课件，关于系统动力学的跟轨迹的一些问题，希望对广大朋友有所帮助。(control system notes)
