Multi Objective Optimization Decision System Based on NSGA-Ⅱ Algorithm

设计一款多目标优化的决策系统,研究集中于调整PID控制器中的KP、KI控制器的增益,使得反馈控制系统满足设计的性能需求。在设计变量参数与给定系统的性能指标之间,设计一种可自动优化增益的参数的算法以满足性能标准的目标。项目设计了PID控制器的增益可以通过NSGA-Ⅱ算法进行调整,从而使得反馈系统的性能指标达到满意的标准。

A multi-objective optimization decision-making system is designed,which focused on adjusting the gain of KP and KI controllers in PID controller to make the feedback control system meet the performance requirements of the design.Between the design variable parameters and the performance index of the given system,an algorithm which can automatically optimize the gain parameters is designed to meet the goal of performance standard. The project designs that the gain of PID controller can be adjusted by NSGA-Ⅱ algorithm, so that the performance index of feedback system can reach satisfactory index.
