能量平衡式自适应飞行控制系统的应用研究

 自适应控制理论在飞机飞行控制方面的应用,国内外已有多年的研究历史,然而达到实用要求的方案为数极少。根据国内飞机飞行控制的发展需要,对能量平衡式方案进行了求实的研究,提出了实用的改进方案。通过试验和原理试飞初步证明,本方案无需试验讯号、结构简单、具有较好的调参收敛性以及基本不受输入讯号形式的影响,应用希望较大。本文扼要介绍了方案选择、设计分析,研制试验以及原理开环试飞的主要结果。重点分析了设计原理。

ON THE APPLICATION OF SELF-ADAPTIVE FLIGHT CONTROL SYSTEM BASED ON ENERGY BALANCE THEORY

In this paper an adaptive flight control system for the longitudinal axis based on energy balance theory is described. A practical improved scheme and design details are presented, and preliminary evaluation from simulation and flight tests is made. The system exhibits better convergence in adjusting parameters and better performance of following up without testing signal. The system's architecture is simple and practicable. Selection of the scheme, design analysis, and brief results of the flight test for the open loop system, especially convergence of adjusting parameters and how to improve the effect of the input signal types are discussed.
