根据飞机作动系统的工作原理,针对液压源能量有限的现状,提出作动系统的功率约束条件。同时考虑操纵面的物理约束,提出了功率受限的操纵面控制分配问题,并给出相应的解决方案。功率受限的操纵面控制分配方法将控制律设计与操纵面任务分配分割为两个模块独立运行,以动态逆控制律为基础,建立控制指令和操纵面间的动态映射关系,考虑操纵面的物理约束并以功率最小作为优化指标,将控制分配问题转化为一个二次规划问题,通过数值求解实现控制系统功率受限下的控制分配。仿真结果表明,考虑功率约束的控制分配方法,可以在系统满足一定稳定性及飞行品质要求的前提下,分配和管理多个冗余操纵面达到指令要求,同时实现系统消耗总功率最小,保证了作动系统的稳定性与安全性。
According to the working principle of aircraft actuation system, aiming at the limited energy status of hydraulic source, the power constraints of actuation system are proposed. At the same time, considering the physical constraints of the control surface, a power-limited control surface assignment problem is proposed and the corresponding solutions are given. The power-limited control surface control distribution method divides the control law design and the control surface task distribution into two modules to run independently. Based on the dynamic inverse control law, the dynamic mapping relationship between the control command and the control surface is established, and the control surface Physical constraints and the minimum power as an optimization indicator, the control distribution problem into a quadratic programming problem, through the numerical control to achieve control of power under the control of the distribution system. The simulation results show that the control allocation considering the power constraints can distribute and manage multiple redundant control surfaces to meet the requirements of the system while meeting certain stability and flight quality requirements. At the same time, the total system power consumption is minimized, ensuring Stability and safety of actuation system.
