| 摘 要： | 为增强飞行器姿控回路与伺服回路的协调匹配性,提升整个姿态控制系统的综合性能,在考虑飞行器伺服回路动态特性的基础上研究其姿态控制方法。以俯仰通道为例,基于多鲁棒面控制和动态面控制理论,提出一种考虑伺服回路动态特性的攻角鲁棒控制方法,有效解决了回路之间的协调控制问题。计算机仿真结果表明:相比于未考虑伺服回路动态特性的攻角控制方案,该控制方案的攻角跟踪效果更好,飞行器姿控外回路和伺服内回路协调匹配性得到提升,且该方案确保了攻角控制系统具备更优越的综合性能指标。研究成果可重点应用于具有高动态和轻质化需求的飞行器姿态控制领域。

| Abstract: | In order to enhance the matching relationship between attitude control loop and servo loop of aircraft, and to improve the comprehensive performance of entire attitude control system, the attitude control approach based on dynamic characteristics of servo loop is studied in this paper. Taking the pitching channel as the example, and based on multiple robust surface control and dynamic surface control approaches, one attack angle controller design method considering servo-loop dynamics is put forward, which can effectively solve the problem of harmonious control between different loops. Computer simulation results show that, compared with other attack angle control schemes without considering servo-loop dynamics, the effect of attack angle tracking is better by using the proposed control scheme, which reflects that the matching relationship between attitude control outer-loop and servo inner-loop is improved. Moreover, it guarantees that the attack angle control system possesses better comprehensive performance. The research findings can be emphatically applied in the attitude control domain of aircraft, which requires higher dynamics and lighter mass. |
