The plots of the Poynting vector might serve to show which part of the wire is mainly responsible for creating the radiated field. The movie of the modulus, |S|, does not give a clear answer, since at close distances the pointing vector reaches high values along the entire wire. The fact that |S| is high along the entire line just means that energy is shifted between the endpoints and the middle region (electric and magnetic field respectively).

遗传算法和神经网络结合的案例，用于非线性规划优化。(Genetic algorithms and neural network case for nonlinear programming optimization)

说明：  运用粒子群算法自动修正BLDC的PID参数，视电脑情况需要运行一段时间才能出结果，可自己修改粒子群参数(The PID parameters of BLDC are automatically modified by particle swarm optimization algorithm, and the results can only be obtained after running for a period of time depending on the situation of the computer. You can modify the parameters of particle swarm by yourself)

说明：  贝叶斯方法将所有参数看作随机变量，将未知参数的先验信息与观测数据综合，再由贝叶斯定理求算出后验概率分布，进而根据后验分布去推断未知参数。(Bayesian method regards all parameters as random variables, synthesizes the prior information of unknown parameters with observation data, calculates the posterior probability distribution by Bayesian theorem, and infers unknown parameters according to the posterior distribution.)

运用MATLAB编程实现遗传算法，数值仿真验证该方法的有效性，表明它能够对函数进行全局寻优。这种实现方法既可以熟悉MATLAB语言，又可以加深对遗传算法的认识和理解，以此来设计智能系统(Programming using MATLAB genetic algorithm, numerical simulation to verify the effectiveness of the method, that it is able to function for global optimization. This method can be familiar with the MATLAB language, but also better understanding of the genetic algorithm can be awareness and understanding in order to design intelligent systems)
