| 摘 要： | 提出了一种改进的抗大气紊流纵向俯仰姿态保持飞行控制系统设计方法;针对大气紊流频谱,建立了包括大气紊流、舵回路和飞机模型为一体的增广模型;运用LQG/LTR对控制系统稳定裕度的补偿作用,设计了抗素流扰动的飞行控制系统,并加入外环PID控制器,提高了系统的动静态性能;最后通过给飞机模型施加摄动来验证飞行控制系统的鲁棒性;仿真结果表明,用该方法设计的飞行控制系统具有良好的动静态品质和较强的抗大气素流干扰的能力,从而使飞行控制系统具有良好的稳定性和鲁棒性.

| Abstract: | An improved method for the longitudinal stance maintainance flight control system under the atmospheric turbulence is proposed.In view of the atmospheric turbulence's spectrum,the augmented model which include atmospheric turbulence,aircraft and rudder loop is established.Using linear quadratic Gaussian control and loop transfer recovery to compensate the control stability margins,design an anti-jamming flight control system for the atmospheric turbulence,and the PID controller is also added to improve the ... |
