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 flight control is to improve the stability and maneuverability of the aircraft so as to enhance its ability to carry out its mission. Based on the recent development both at home and abroad and some major research results, the current research on current UAV flight control is summarized, including feedback linearization, backstepping control, sliding mode variable structure control, nonlinear H ∞ and μ integrated robust control and other nonlinear design methods, analyzed their own characteristics, and then for the traditional PID control algorithm has many shortcomings, introduced several common in the UAV flight control of intelligent PID control, the final analysis The existing problems and the future direction of development.
