为了解决翼伞空投系统在实际工程中航迹跟踪操纵频繁问题,提出一种基于模糊逻辑的航迹跟踪控制算法。首先,建立翼伞系统的运动模型,根据操纵特性设计飞行控制方案,控制信号操纵翼伞左右伞绳的下拉、保持和回复操作,实现系统对指定航迹的跟踪。其次,仿真了相关因素对控制性能的影响。仿真结果表明:该模糊控制方法简单有效,易于实现,解决了翼伞航迹跟踪时操纵频繁问题,完全满足航迹跟踪的要求。

In order to solve the problem of frequent manipulation when parafoil airdrop system is tracking a trajectory in actual engineering, presents a fuzzy logic-based tracking control algorithm. First, the motion model of parafoil system was established, flight control scheme was developed based on the handling characteristic, and the control signals manipulate the left and right sides suspension line of parafoil into the drop-down, maintain and/or reset operation. As a result, system can track the authorized path. Secondly, the influence of the interrelated factors to control performance were simulated. Simulation results show that： the fuzzy control method is simple and effective, easy to implement, solves the problem of frequent manipulation of suspension line during path tracking, fully meetting the requirements of path tracking.
