针对具有不确定性及外部干扰的着舰轨迹精确跟踪控制问题,提出了一种对侧向自动着舰引导控制内外回路进行综合化设计的方法。使用特征结构配置实现侧向模态解耦跟踪控制,同时设计L1自适应控制器以补偿系统由于不确定性、舵面故障、舰尾流干扰带来的不利影响,将其应用到侧向自动着舰控制系统。仿真结果表明,对内外回路进行综合设计的着舰引导控制律具有抑制不确定性及干扰的能力,能够实现对侧向自动着舰轨迹的精确跟踪控制。
Aiming at the problem of precise tracking control of landing trajectory with uncertainties and external disturbances, a method of integrated design of lateral automatic guided guided internal and external circuits is proposed. The lateral modal decoupling tracking control is implemented by using the feature configuration, and the L1 adaptive controller is designed to compensate for the adverse effects of the system due to the uncertainty, the rudder failure and the wavy wake, and applied to the lateral automatic Landing control system. The simulation results show that the guidance control law for the integrated design of internal and external circuits has the ability to restrain the uncertainty and interference, and can realize the accurate tracking control of the lateral automatic landing trajectory.
