摘　　要：为提高舰载直升机着舰任务的成功率和安全性,提出基于H_(∞)控制算法的姿态指令姿态保持(attitude command attitude hold,ACAH)响应类型设计的方法。通过分析舰载直升机着舰时的任务科目基元及美军直升机飞行品质规范ADS-33E,选择舰载直升机在悬停进近过程中纵轴的操纵响应为ACAH响应类型,基于H_(∞)混合灵敏度方法设计鲁棒H_(∞)控制器,通过仿真分析验证鲁棒控制器的抗扰特性和ACAH控制效果,并进行飞行品质评定。结果表明:该设计具有较高的抗扰特性,直升机纵向操纵响应为ACAH响应类型,飞行品质达到等级一。In order to improve the success rate and safety of shipboard helicopter landing missions,a design method of attitude command attitude hold(ACAH)response type based on H_(∞)control algorithm is proposed.By analyzing the mission subject primitives of the carrier-based helicopter when landing on the ship and the U.S.helicopter flight quality specification ADS-33E,the control response of the longitudinal axis of the carrier-based helicopter during the hovering approach is selected as the ACAH response type.The robust H_(∞)controller is designed based on the H_(∞)mixed sensitivity method,and the anti-disturbance characteristics and ACAH control effect of the robust controller are verified through simulation analysis,and the flight quality is evaluated.The results show that the design has high anti-interference characteristics,the helicopter’s longitudinal control response is ACAH response type,and the flight quality reaches level 1.
