| 摘 要： | 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.

Design of L1 adaptive controller for lateral-directional automatic carrier landing |
| |
| Abstract: | To improve the automatic carrier landing system (ACLS) precision with uncertainties and external disturbance,L1 adaptive based eigenstructure assignment is applied to the tracking control for inner and outer loop of lateral-directional carrier landing.Model decoupling tracking control is realized by eigenstructure assignment method.L1 adaptive with piecewise continuity is used to compensate mismatched uncertainties and external disturbance.Simulation results show that L1 adaptive can deal with system uncertainties,actuator failures and external disturbance.Simulation study shows that the controller with integrated design has good tracking and disturbance rejection ability. |
