摘要
传统综合飞行/火力控制系统使用飞/火耦合器或者协调控制器实现系统综合,不利于整个系统的功能解耦。针对某型武装直升机的空-地射击模态设计了基于多重递阶控制结构的IFFC系统。第一重应用H∞二自由度设计方法实现直升机三姿态通道间的解耦控制,解决姿态跟踪问题。第二重通过火控解算,向第一重提供期望的姿态角指向。该结构极大减弱了各重回路间的功能耦合。仿真结果表明,系统具有良好的作战性能和较强的鲁棒性。
Traditional integrated control system used a fire/fly coupler or a coordinator to realize integration, which did damage to the functional uncoupling of whole system. An Integrated Flight/Fire Control （IFFC） system for air-to-ground gunnery of helicopter is designed, based on the theory of multistrata hierarchical control structure, in which the two-degree-of-freedom H∞method has been used in the first loop to realize the uncouple control among the tree attitude channels of helicopter, so that the problem of attitude tracking control could be solved, and the second loop has been designed to provide anticipant attitude for the first loop with the fire control algorithm. Affection among levels has been greatly decreased. Good performance and strong robustness have been demonstrated through simulation results.
