摘　　要：对直升机半滚倒转机动动作开展机理分析,将机动动作进行分段设计。在半滚段设计滚转角速度保持,根据滚转角调整总距输入量;在俯冲拉起段设计俯仰角速度保持,根据俯仰角调整总距输入量,并在阻尼回路引入自抗扰控制算法,以提高控制系统的扰动抑制能力。针对有风/无风2种飞行环境,通过视景仿真技术对UH-60直升机开展仿真,结果表明,直升机可以在4.5 s内完成半滚倒转机动飞行,验证了该设计控制策略是合理的,飞行控制律具有良好的抗扰性能。Based on the mechanism analysis of helicopter half roll reverse maneuver,the maneuver is designed in sections.The roll angle rate holding control is designed,the collective is adjusted according to the roll angle in the half-roll stage.The pitch angle rate holding control is also designed,with the collective is adjusted according to the pitch angle during the pull-up stage.The active disturbance rejection control algorithm is introduced into the damping loop to improve the disturbance resisting capability of the control system.The UH-60 helicopter is used by visual simulation technology for both windy and normal flight environments.The numerical results show that the helicopter can complete the Split-s maneuvering flight within 4.5 s,which verifies that the control strategy designing in this paper is reasonable and the flight control law has a good anti-disturbance performance.
