本文利用经典控制与现代控制理论相结合的方法,分析、设计了一种复杂的时变非线性随机控制系统——空一空射击模态的综合火力/飞行控制(IFFC)系统。文中给出了飞行控制系统的构成与设计结果,建立了一种基于惯性座标系的指挥仪型火控解算模型,讨论了火飞耦合控制律的构成特点,设计了目标状态估值的卡尔曼滤波器,最后进行了整个IFFC 系统的数字仿真。大量仿真结果,特别是空战状态下飞机倒飞机动模态的自动进入和退出,表明了本文所设计的IFFC 系统具有良好的性能和一定的实际意义。
In this paper, by combining the classical control theory and modern control theory, a complex time-varying nonlinear stochastic control system-air-to-air fire mode integrated fire / flight control (IFFC) system is analyzed and designed. In this paper, the composition and design results of flight control system are given. A model of command and control fire control based on inertial coordinate system is established. The characteristics of the control law of fire and fly coupling are discussed, and the target state estimation Kalman filter, finally carried out the entire IFFC system digital simulation. A large number of simulation results, especially the automatic entry and exit of aircraft maneuvering modes in the air combat state, show that the IFFC system designed in this paper has good performance and certain practical significance.
