摘　　要：针对多操纵面飞机弱冗余系统调参工作量大、控制能力低的问题,基于加权伪逆提出了控制分配模态参数调节方法,揭示了弱冗余控制参数与出舵量之间的内在机理。在建立加权伪逆控制分配模型的基础上,定义了弱冗余剩余效能矩阵。推导了弱冗余加权伪逆分配参数的调节关系,即出舵量不随参数变化,特定情形下所有操纵面指令均无影响。仿真结果验证了方法的有效性,并通过施加微小摄动改善了多操纵面控制能力。With regard to the huge regulation workload and low control capability for multi-control surfaces aircraft with weak redundancy,a parameters regulating method based on the weighted pseudo-inverse is proposed,which finds out the inherent essence between the weak control parameters and control surface deflection. After building the weighted pseudo-inverse allocation model,a residual efficiency matrix about weak redundant is defined. The parameters regulating relation of the weighted pseudo-inverse allocation with weak redundancy are obtained,which included that the rudder output does not vary with the parameters,and all the control surface commands have no effect under certain circumstances. The simulation results validate the effectiveness,in which the control capability of multi-control surfaces is improved by adding small perturbation.
