摘　　要：针对操纵面饱和时混合优化控制分配效率低的问题,提出一种包含执行器动态的多操纵面变参数控制分配策略.考虑执行器物理约束和动态特性,构建多操纵面飞机控制分配模型.以权系数变换矩阵为参数,将非线性混合优化控制分配律线性化.分别建立忽略和包含执行器动态的变参数控制分配线性矩阵不等式优化模型,并研究控制分配系统对参数变化的灵敏度.仿真结果验证了变参数动态控制分配策略的有效性.To overcome the allocation low efficiency for saturated effectors, a parameter-varying control allocation scheme including actuator dynamics is presented for the overactuated aircraft. By considering the actuator constraints and dynamics,the control allocation model of the overactuated aircraft is built. The nonlinear control allocation law of mixed optimization is linearized through taking the weight coefficients matrix as varying parameters. The parameter-varying control allocation model is formulated in terms of the linear matrix inequality, in the case of neglecting actuator dynamic or not, respectively.Then the parameters sensitivity for control allocation is studied. The simulation result shows the effectiveness of the proposed parameter-varying dynamics control allocation scheme.
