摘要
为了进一步提高着舰精度,针对具有舰尾流扰动、参数不确定以及非线性干扰的着舰控制问题,设计L1自适应增广控制器。该控制器具有分段连续自适应律,用于补偿着舰纵向内回路中存在的舰尾流干扰和不确定性的不利影响。将其应用到舰载机自动着舰纵向控制系统。仿真结果表明:L1自适应控制器能够处理参数不确定性等不利情况,并且具有抑制稳态尾流的能力,实现了自动着舰轨迹精确跟踪控制。
For further improving landing precision, aiming at the landing control at situation such as ship wake disturbance, parameter uncertainty, and non-linear disturbance, design L1 adaptive augmentation controller. The controller has piecewise continuous adaptive law to compensate bad influence of ship wake disturbance and uncertainty in ship longitudinal inner loop. Use it in carrier-based aircraft automatic landing longitudinal control system, the simulation results show that L1 adaptive controller can deal with system uncertainties, restrain steady ship wake, and realize automatic lading trajectory precise tracking control.
