摘　　要：针对舰载机着舰过程中舰尾流扰动引发的航迹跟踪精度下降问题,设计了有效抑制舰尾流的纵向自动着舰引导律。以F/A-18舰载机为研究对象,根据其气动参数建立含扰动变量的非线性着舰模型,建立着舰平衡点处的线性小扰动模型,对模型的系统及扰动矩阵扩展化处理,采用正不变集和二次有界系统的相关理论,阐述抑制舰尾流扰动理论和算法的实现过程,推导相应的线性矩阵不等式,得出有效抑制有界扰动的自动着舰预测控制算法。将自动着舰引导律作用于半物理仿真平台的非线性着舰模型上,验证了抑制扰流和自动着舰有效性。Regarding the accuracy decrease of trajectory tracking caused by air wake in the carrier landing,a longitudinal automatic landing guidance law rejecting air wake is proposed.The F/A-18 carrier-based aircraft is chosen as the researched object in this paper,and the nonlinear landing model including disturbance variable is established according to aerodynamic parameter of the F/A-18.The linear perturbation model is built in landing balance point,and the system and perturbation matrices are enlarged.The theories of positively invariant set and quadratic boundedness are adopted so that the theoretical derivation and implementation process of rejecting air wake disturbance is discussed.The linear matrix inequalities(LMIs)are employed.An automatic landing model predictive control(MPC)effectively rejecting air wake is acquired.The automatic landing guidance law is utilized on a semi-physical simulator with nonlinear landing model to verify the effectiveness of rejecting air wake and automatic landing.
