摘要
飞行控制的基本目的是改善飞机的稳定性和操纵性,从而提高执行任务的能力。结合近年来国内外的发展状况和一些主要的研究成果,首先对当前无人机飞行控制领域中的最新研究进行了概述,包括反馈线性化、反步控制、滑模变结构控制、非线性H∞和μ综合鲁棒控制等非线性设计方法,分析了各自的特点,然后针对传统PID控制算法存在的诸多缺陷,介绍了几种在无人机飞行控制中常见的智能PID控制,最后分析总结了存在的问题及未来的发展方向。
The basic purpose of the flight control is to improve the stability and maneuverability of aircraft to enhance mission capability.Based on the current research level and achievements at home and abroad,our article mainly separats it into three parts.First,the updated research achievements in the domain of the current UAV flight control are summarized,including the nonlinear control design methods,such as feedback linearization,backstepping control,sliding mode variable structure control,robust control of H∞control and μ synthesis control,and so on.Meanwhile,the characteristics of such methods are also analyzed respectively.Second,several intelligent PID control methods commonly used in the UAV flight control are introduced,in consideration of the defects existing in traditional PID control algorithm.Finally,several key existing problems and future research directions are pointed out.
