摘要

摘要: 以一种短距起降战斗机的飞行/推进综合控制系统设计为背景,对分散控制如何保持集中控制的性能和鲁棒性的问题提出利用优化的思想设计分散控制器.首先采用遗传算法设计集中控制器,作为分散控制的性能参考,然后给出具有接口变量的分散控制器设计方法,通过分析得出影响分散控制性能的关键因素,并通过数学推导得到以频率加权矩阵为设计参数的分散控制性能表达式,将分散控制器设计转化为优化问题,采用遗传算法求解得到分散控制器.分散控制器设计中同时用到了一种改进的平衡降阶方法.通过仿真和结构奇异值分析验证了这种优化设计方法可使分散控制达到集中式控制的性能和鲁棒性.

Abstract: With an integrated flight/propulsion control system of a short take-off and landing fighter as design plant,an optimization design approach for decentralized control was proposed in order that it can maintain the performance and robustness of its corresponding centralized control.A centralized controller was firstly designed by using genetic algorithm as the performance reference for the decentralized controllers.The optimization design method for the decentralized controllers with interface variable was then provided.A critical element affecting decentralized control performance was analyzed and the decentralized control performance expression using frequency weighted matrix as design parameter was deduced.The problem of designing the decentralized controllers was converted into optimization problem solved by genetic algorithm.An improved balanced reduction method was also used in decentralized controller design.The simulation and structured singular value analysis show that the proposed optimization design method is so effective that the decentralized control system approximately reaches the same performance and robustness achieved by centralized control system.
