| 中文摘要 |
| 翼伞系统是一类特殊的柔翼飞行器, 由于其飞行速度较低, 容易受到风场的影响. 针对翼伞系统在较大风
场中难以准确跟踪归航轨迹、实现精确着陆,因此将风场中平均风的影响在轨迹规划中予以考虑,采用一种改进的
粒子群算法(particle swarm optimization, PSO)优化分段归航轨迹; 将紊流的影响作为外界的干扰, 由线性自抗扰控
制器(linear active disturbance rejection controller, LADRC)进行修正. 仿真结果表明, 该归航控制方法对提高翼伞系
统在较大风场环境下的抗风性能和归航精度有重要意义. |
| 英文摘要 |
| The parafoil system is a very unique class of ?exible winged vehicle, due to the low speed characteristics, it
is vulnerable to wind ?elds. Since it is dif?culty for the parafoil system to track the desired homing trajectory precisely and
achieve accurate landing in a large wind environment, the impacts of mean wind are taken into consideration in the stage
of trajectory planning, and a multiphase homing trajectory is designed and optimized based on a modi?ed particle swarm
optimization (PSO) algorithm; in the meantime, the in?uences of turbulence are regarded as the external disturbances and
amended by linear active disturbance rejection controllers (LADRC). Simulation results show that the proposed homing
control strategy is of great importance to improve the homing accuracy and anti-wind ability for achieving set point homing
of the parafoil system in large windy conditions. |
