espopso,一种高级PSO算法，通过改变粒子数目达到较好的优化，如需改变测试函数，须将主程序内所有测试函数名字全部改变。-espopso, an advanced PSO algorithm, by changing the number of particles to achieve a better optimization, need to change the test function, all test functions within the main program shal

在matlab, 利用粒子群算法（PSO）实现函数极值优化-In matlab, using particle swarm optimization (PSO) to achieve function extreme optimization

粒子群算法用于优化求解函数最小值，此算法收敛速度快，很快找到最小值。-Particle Swarm Optimization (PSO) is used to optimize the minimum value of the function. The algorithm converges quickly and finds the minimum value.

PID控制器参数主要是人工调整，这种方法不仅费时，而且不能保证获得最佳的性能。PSO已经广泛应用于函数优化、神经网络训练、模式分类、模糊系统控制以及其它应用领域，本案例将使用PSO进行PID控制器参数的优化设计。-The main parameters of PID controller are manual adjustment. This method is not only time-consuming, but also can not guarantee the best perfor
