建立了基于置信度较高的飞行动力学模型的直升机平台侧向起降轨迹优化最优控制模型,使用间断有限元法离散该模型,使用序列二次规划算法(SQP)进行求解,得到直升机平台上侧向起降单发失效后的最优操纵和飞行轨迹。以UH-60直升机为算例,分析了不同操纵速率加权系数对以最小下降高度为目标函数的继续起飞最优化轨迹的影响;研究了不同初始高度对以安全着陆速度为目标函数的中断起飞最优化轨迹的影响。
The optimization model of helicopter platform lateral take-off and landing trajectory optimization based on high confidence flight dynamics model was established. The discontinuous finite element method was used to discretize the model, and the quadratic programming algorithm (SQP) was used to solve the helicopter platform On the side of the single take-off and landing after the failure of the optimal control and flight path. Taking the UH-60 helicopter as an example, the influence of different steering rate weighting factors on the take-off optimal trajectory with the minimum descent altitude as the objective function was analyzed. The effects of different initial altitudes on the takeoff takeoff with the safety landing speed as the objective function Optimize the trajectory of the impact.
