针对某飞翼式无人机飞行过程中出现舵面破损情况,提出了一种具有容错能力的舵面权限动态分配算法。针对舵面无故障和副翼两侧完全破损故障,分析比较了典型舵面分配算法和动态分配算法的性能。分析结果表明:舵面无故障时,在满足约束条件的情况下,由动态分配算法实现的舵面分配其滚转和俯仰操纵力矩可达范围大于由典型舵面分配算法实现的,有利于克服较大的俯仰或滚转干扰,而在升降舵或者副翼出现破损故障时具有更强的容错能力。
Aiming at the damage of the rudder surface during the flight of a flying wing UAV, a dynamic allocation algorithm of rudder authority with fault tolerance is proposed. Aiming at no fault on the control surface and complete damage on both sides of the aileron, the performance of the typical control surface allocation algorithm and dynamic allocation algorithm is analyzed and compared. The analysis results show that the rudder surface assignment by the dynamic assignment algorithm achieves a greater reach range of roll and pitch maneuvering torque than the rudder surface assignment algorithm when the rudder surface is fault-free, which is beneficial to overcome Larger pitching or rolling disturbances and greater fault tolerance in the event of damage to the elevator or aileron.
