Aplication PID in Matlab

遗传算法是兼职编码求函数的极大值程序，比较详细。(A function or part-time coding genetic algorithm (ga) is a great value program, more detail.)

电力系统潮流计算程序，C++程序，电力系统稳态时的小作业(Power flow calculation program, small operations C++ procedures, steady state power system)

本文先简要介绍了矩阵的积分和微分的定义；接着通过弹簧-质量块儿-阻尼器系统的例子，阐述了求解常微分方程数值解的常用方法；最后，在前两部分的基础上，总结了用MATLAB求解形如_X(t) = f(X(t); t) 矩阵微分方程数值解的方法。(In this paper, the definition of integral and differential of matrix is briefly introduced. Then the common method of solving numerical solution of ordinary differential equation is described by the example of spring mass block damper system. Finally, on the basis of the first two parts, the solution of the form of _X is summed up by MATLAB. (T) = f (X (T); t) numerical solution of matrix differential equations.)

在过程控制中，按偏差的比例（P）、积分（I）和微分（D）进行控制的PID控制器（亦称PID调节器）是应用最为广泛的一种自动控制器。(In process control, according to the ratio of deviation (P), integral (I) and differential (D) to control the PID controller (also known as PID regulators) is the most widely used an automatic controller.)

用matlab分析由n个单胞组成的桁架在受到最外节点处的集中力是的位移及应力应变，并对整个结构进行优化设计。(Matlab analysis by single cell formed by the n truss subjected to the most outside the nodes in the concentration of power is the displacement, stress and strain, and the entire structure is optimized.)

说明：  matlab语言中画箭头的例子，通过修改可以画各种形状的箭头。(arrow plot in matlab)

简单介绍了intrans的用法，并简单那介绍了研究生写开题报告时应该注意的问题(Intrans introduced the use of simple, and it introduces the students to write a simple opening report should pay attention to the problem)
