摘要
研究了综合火力／飞行控制系统（ＩＦＦＣＳ）的模糊控制问题。首先给出飞机纵向运动的火力／飞行控制系统的数学模型，然后讨论了基本模糊控制器的结构方案和设计过程。在分析了不同量化因子及比例因子对控制特性的影响后，对基本模糊控制器进行了改进，提出了分段因子模糊控制器和经过一次修正的模糊控制器的设计思想。最后，对包含模糊控制器的ＩＦＦＣＳ进行了计算机仿真。仿真结果表明，对ＩＦＦＣＳ采用模糊控制方法是可行的，它使综合火力／飞行控制系统具有较好的快速响应性能，控制效果是满意的。
The fuzzy control of integrated fire/flight control system (IFFCS) is studied.First, the mathematical model of IFFCS in a vertical plane is given. Then, the structure and the design of the basic fuzzy controller are discussed. After analysing the effect of different parameters k., kc and ku on control performance,the basic fuzzy controller is improved. The fuzzy controller with separating-stage factors and a modified one are proposed. Finally, the computer simulation of IFFCS with fuzzy controllers is carried out. The simulation results show that it is feasible to apply the fuzzy control method to IFFCS. Better performance is produced in fast responses of IFFCS. The control effect is satisfactory.
