摘要
对飞行/推进综合系统分散控制如何保持集中式控制性能的问题,研究了一种分散控制系统设计方法。首先设计集中式控制器使系统达到最优性能,以此作为性能参考,然后引入分散控制结构处理飞机与发动机之间的耦合作用,对其中的接口变量选取问题进行了分析,给出了分散控制系统的设计步骤,最后通过仿真验证了这种设计方法可以使分散控制具有与集中式控制相同的指令跟踪和解耦性能。
A new method was developed to deal with the problem that decentralized integrated flight/propulsion control system needed to keep centralized control performance.A centralized controller was firstly designed as the baseline of optimal performance for decentralized control system.The decentralized control structure was introduced to decentralized control system to handle the coupling between airframe and engine.The selection approach of interface variable in this structure was provided and only one interface variable was chosen.The design steps of each subcontroller in decentralized control system were given.Lastly,comparing decentralized control simulation results with centralized control,the decentralized control system matches the closed-loop command tracking and decoupling performance achieved by centralized control.
