摘要:

针对无人机着舰这一特殊环境,为克服系统摄动、未建模动态及各种环境干扰因素的不良影响,从工程实现易行性出发,提出一种新的积分滑模着舰飞行控制方法,避免其受传统积分切换函数滑模控制方法的应用限制,并采用自适应模糊系统抵消外界干扰带来的误差,逼近滑模控制器中的切换项,从而有效降低舵面的抖振。搭建自动着舰综合仿真平台,以国外现役某小型舰载无人机为例,仿真结果表明,该自动着舰系统能较好地克服各种因素的影响,实现无人机安全着舰,着舰性能符合要求。

Abstract:

To overcome the adverse effects of various disturbances on unmanned aerial vehicle (UAV) landing, a new sliding mode control method from the point of engineering realization is proposed to avoid restrictions in the traditional integral sliding mode, and the adaptive fuzzy system is used to offset interference errors.The sliding switching is approximated to effectively reduce chattering. Finally, an autonomous landing simulation platform is built. Take an active service small carrier UAV as the research object, and the results of the simulation indicate that this system can effectively overcome various factors affecting landing,such as sea state, navigation error, airwake, realizing the UAV safe landing, and the landing performances meet the design requirements.
