基于实数编码遗传算法的PID整定,采用误差绝对值积分性能指标作为参数选择的最小目标函数-real-coded genetic algorithm PID tuning, integral absolute error performance parameters as the minimum objective function

计算函数的积分，用的是辛普森积分公式，计算精度与matlab比较比较高-Evaluate the function of the integral, using Simpson integration formula, the accuracy is relatively high compared with matlab
