可重构零空间控制分配算法及流程规划

Reconfigurable Null-space Control Allocation Algorithm and Flow Planning

针对飞机正常情况和舵面故障情况下的控制分配算法展开研究。根据控制效能矩阵的特点设计了性能指标,并给出了对应的最优逆控制。对带约束的一般控制分配问题,采用零空间横截方法进行了再分配。设计了针对舵面卡死故障的重构控制律。结合某飞机仿真平台,进行了卡死故障的重构仿真,结果表明,控制分配算法能够在故障状态下完成对指令的精确跟踪。

Control allocation algorithm for the aircraft during normal flight and case of actuator faults was studied. Performance Index was designed according to the characteristic of the control effectiveness matrix,and the optimal inverse matrix was presented. Redistribution used null- space intersection was given for constrained control allocation problem. Reconfiguration control law for situation of actuator blocked was designed. Finally,a simulation for reconfiguration of actuator blocked was made under an aircraft simulation platform,the results show that the allocation method makes the system stability,both cases of fault and normal flight,which satisfied control requirements.
