综合火力飞行控制(IFFC)系统设计必须解决二个基本问题:①IFFC 系统的数学描述与分析;②IFFC 控制器设计。本文详细讨论了前者。首先研究了一般的可测状态(MSV)系统的标准型、状态空间实现、稳定性问题。随后给出了适用于IFFC 系统设计的飞机动力学模型,推导了空对空射击火控模型,从而导出了描述IFFC 系统的具有纵侧分离性的MSV 模型,并给出了IFFC 系统的部分分析结果。IFFC 系统的MSV 模型兼具输入输出(IO)模型和状态空间(SS)模型的特征,同时更符合工程设计的要求。
Integrated Fire Flight Control (IFFC) system design must address two basic issues: ①IFFC system mathematical description and analysis; ②IFFC controller design. This article discusses the former in detail. First of all, we study the standard type, state space realization and stability of the general measurable state (MSV) system. Then the aircraft dynamics model which is suitable for the design of IFFC system is given and the fire-control model of air-to-air firing is deduced. The MSV model describing vertical separation of IFFC system is derived and the partial analysis of IFFC system is given result. The IFFC system’s MSV model combines the features of both input and output (IO) models and state space (SS) models, while more in line with engineering design requirements.
