摘要
有人直升机精确着舰是亟待解决的一项技术难题。面向着舰任务需求,本文构建了人机一体式仿真模型,选取典型着舰任务科目基元(MTE)。人机仿真模型包括驾驶员模型、直升机飞行动力学仿真模型、不同构型下直升机飞行控制律以及包括舰面环境综合仿真模型。上述模型在统一的仿真空间内定义并互相进行交联,可有效地对着舰任务中的人机闭环系统进行模拟。基于上述仿真模型,进行了人在回路试验仿真,结果表明响应类型平移速率(TRC)可以有效地提升有人直升机着舰任务成功率,这对着舰控制律的设计具有显著的意义。
Accurate position control is an urgent demand for manned helicopter landing.To achieve this objective,a pilot-rotorcraft simulation model is established,and meanwhile typical mission-task elements(MTE)for helicopter landing are selected.The overall model includes a pilot model,helicopter flight dynamics,various types of control laws and a simulation model for the deck environment.All the parts of the simulation model are defined in the same working space and connected with each other.Resorting to experiments,the established pilot-rotorcraft simulation is able to provide objective evaluations for helicopter control laws of different types.Application results demonstrate that TRC response type can effectively improve the success rate of manned helicopter landing mission,which provides practical guides for design of control law for helicopter landing.
