在翼伞系统的状态空间模型的基础上,分析了翼伞的归航轨迹,给出翼伞轨迹跟踪控制问题的数学描述。针对翼伞归航飞行过程中,受到较大的外干扰及不确定性影响,提出基于模糊干扰观测器(FDO)的非线性预测控制策略,设计了翼伞归航系统航迹跟踪控制器。通过仿真试验,表明该飞控系统具有良好鲁棒特性和抗干扰特性。
Based on the state space model of the wing umbrella system, the flight path of the wing umbrella is analyzed, and the mathematical description of the tracking control of the wing umbrella is given. In the course of parachute parachute flight, the nonlinear predictive control strategy based on fuzzy disturbance observer (FDO) is proposed under the influence of large external disturbances and uncertainties. The trajectory tracking controller of parachute parachute system is designed. Simulation results show that the flight control system has good robustness and anti-jamming performance.
