摘要
文中对于PID参数整定问题,通过分析比较不同组合的性能指标,在基于多目标智能优化算法下进行PID参数整定。该方法基于非支配排序多目标遗传算法(NSGA-Ⅱ),在采用不同性能指标组合后生成的不同目标函数空间,通过Matlab进行控制系统仿真后,对输出的阶跃响应曲线进行了分析和比较,从而寻找到了IAE、ISE以及控制输入的平方项作为最优的三目标性能指标组合。
The PID parameter optimization based on multi-objective evolutionary algorithm is proposed by analy- zing performance metrics to compare different combinations. The method is based on the non-dominated sorting genetic algorithm II （NSGA-II） for generating different targets after the introduction of different indicators combination of properties function. Analysis and comparison the curves of step response output is made through Matlab simulation of the control system to find the optimal combination of the performance indicators IAE, ISE and squared term control
