气动力／直接力复合控制导弹的线性二次型最优控制设计

摘要

Linear quadratic （LQ） sile with tails and reaction jets. Optimal ulator （LQR） problem. The metrical optimal control design method is applied to a dual-controlled misstate feedback law is obtained by solving the linear guadratic regangular velocity and linear acceleration are used to form the output feedback law by converting optimal state feedback into output feedback, so the difficulty in realization of the state feedback law caused by the unmeasurable angle of attack can avoid. Compared the simulation results of dual control with aero-only control or jet-only control, which show that the designed dual control system has great superiority in the rapid response ability.%对应用直接力和气动力复合控制的弹体，进行线性二次型最优控制设计。通过求解线性二次型调节器获得最优状态反馈律，将最优状态反馈转换为等价的输出反馈，角速度和加速度的测量值就可用于输出反馈律的形成，避免了含有不可测量状态攻角的状态反馈律在实现上的困难。复合控制和气动力（或直接力）单独作用时的仿真对比结果说明，所设计的复合控制系统具有快速响应的优越性。
