在飞机设计中,应用不同的驾驶员模型来预测驾驶员诱发振荡(PIO)是避免人机系统出现不良耦合的重要途径之一。以人-机闭环系统为研究对象,以某一电传飞机为例,采用Ⅱ型PIO的开环发生点OLOP评估准则,分别使用增益驾驶员模型和修正Neal-Smith驾驶员模型对人机闭环系统中的PIO易感性进行了分析、评估,对比研究了不同驾驶员模型对OLOP评估准则评估结果的影响。仿真结果表明:不同的驾驶员模型对Ⅱ型PIO评估准则(OLOP)的评估结果有较大的影响,相同驾驶员模型下不同的驾驶员增益对评估结果也有影响。在使用OLOP评估准则时应充分考虑驾驶员模型对评估结论的影响。
In aircraft design, applying different driver models to predict driver induced oscillation (PIO) is one of the important ways to avoid the undesirable coupling of man-machine system. Taking the human-machine closed-loop system as the research object and a teletype aircraft as an example, the open-loop OLOP evaluation criteria of type II PIO are used. The gain driver model and the modified Neal-Smith driver model are used respectively to simulate the man-machine loop PIO susceptibility in the system was analyzed, evaluated, and the impact of different driver models on the evaluation results of OLOP assessment criteria was compared. The simulation results show that different driver models have a great influence on the evaluation results of Type II PIO Evaluation Criteria (OLOP), and different driver gains under the same driver model also have an impact on the evaluation results. When using the OLOP assessment criteria, the impact of the driver model on the assessment conclusion should be fully taken into account.
