摘要
针对强冗余多操纵面飞机参数多、难调节的问题,基于加权伪逆提出了控制分配模态参数调节方法,揭示了控制参数与出舵量之间的内在机理。引入虚拟控制指令,建立了加权伪逆控制分配模型。定义了一种剩余效能矩阵,从理论上推导了强冗余加权伪逆分配参数调节的规律,得到出舵量与对应参数是负相关的,特定情形下对方向舵指令无影响。仿真结果验证了该方法的有效性。
With regard to the design of excessive regulated parameters for multiple effectors aircraft with strong redundant,a parameters regulation method based on the weighted pseudo-inverse is proposed,which finds out the inherent essence between the control parameters and effector deflections.By introducing the virtual control instruction,the weighted pseudo-inverse allocation model is built.Based on the defined residual efficiency matrix,the parameters regulation laws of the weighted pseudo-inverse allocation with strong redundant is obtained and proved in theory.It contains that the effector deflections are negatively correlated with corresponding parameters and in specific situation the rudder deflections are unrelated.The simulation results validate the effectiveness.
