自动空中加油杆LQR控制器设计

针对硬式空中加油过程中加油杆在外界干扰下可能存在不稳定的问题,本文提出了一种线性二次型最优控制方法。首先建立加油杆的数学模型,推算出其状态空间方程,然后设计相应的控制律并搭建simulink仿真模块。仿真结果表明,加入线性二次型最优控制的反馈单元后,飞机的俯仰角和滚转角很快收敛为0,系统响应稳定。

LQR controller design for boom air-refueling bar

Aiming at the problem that the refueling bar may be unstable under the outside interference when the aircraft in the boom air-refueling, this article presented a linear quadratic optimal control method. Firstly, we established the mathematical model of the refueling bar and created a state space equation of the model, and then designed the corresponding control law and built the simulink simulation module. Simulation results showed that in linear quadratic optimal control of the feedback unit, the pitch angle and roll angle of the aircraft quickly converged to zero. The system response was stable.
