controlled Half wave rectifier circuit with inductive load and gives positive half cycle and block negative half cycle.

降压它激推挽DC/DC的电路,输入24V直流电压，输出8V直流电压，主要起降压隔离的作用(The push-pull DC/DC circuit)

说明：  核极限学习机是一种单隐层前馈神经网络(the single-hidden layer feedforward neural networks,SLFNs),其只需要设置隐藏层节点数,然后采用最小二乘法计算出权值即可。因此,核极限学习机在学习速度和泛化能力上具有很大优势。(Kernel limit learning machine is a single hidden layer feedforward neural networks (slfns). It only needs to set the number of hidden layer nodes, and then use the least square method to calculate the weight. Therefore, the kernel limited learning machine has a great advantage in learning speed and generalization ability.)

在matlab开发环境下，实现对直流电动机调速系统的仿真(MATLAB development environment to achieve the simulation of DC motor speed control system)

MATLAB作为一款无比强大的科学计算工具，在可以自由编程的同时，MATLAB也为我们封装好了一些功能，以工具箱的形式供我们使用，下面我就详细介绍一下MATLAB工具箱的使用方法。(MATLAB as a powerful tool in scientific computing, free programming at the same time, MATLAB also provide us a good package some functions to toolbox forms for our use, below I will detail the use of methods about MATLAB toolbox.)

使用支持向量机进行非线性回归，得到非线性函数y=f(x1,x2,…,xn)的支持向量解析式，求解二次规划时调用了优化工具箱的quadprog函数。本函数在程序入口处对数据进行了[-1,1]的归一化处理，所以计算得到的回归解析式的系数是针对归一化数据的，仿真测(Using support vector machines non-linear regression)

说明：  数学建模中的程序编写，矢量数据的显示，达到建模过程中用户的需求(Programming in the mathematical modeling and display of vector data, to the needs of users in the modeling process)

改进的粒子群算法，有更好的性能，提高了算法的搜索能力(Improved particle swarm optimization, better performance, improved search ability of the algorithm)
