摘　　要：为了获得驾驶员和飞机良好的匹配特性,使用基于人机闭环参考模型的方法将飞行品质的要求引入优化算法,进行飞行控制系统设计。首先使用CAP准则建立飞机等效系统模型。然后,基于时域Neal-Smith准则,通过多目标优化算法一次性得到在不同任务条件下的最优驾驶员模型。根据需要选择相应的驾驶员模型,并与飞机等效系统模型组成人机闭环参考模型,进行飞行控制设计多目标优化。仿真结果显示,文中的算法不仅可以整定控制器参数,根据任务需求选取最优驾驶员模型,还可以利用优化结果进行PIO易感性的分析。Sections 1 and 2 of the full paper explain what we believe to be a fairly successful exploration.Their core consists of：（1） to match the pilot and the aircraft,with the man-vehicle closed loop reference model,we introduce the flight quality requirements into the optimization algorithm to design the aircraft flight control system;（2）we establish the equivalent model of the aircraft with the CAP criterion;（3） using the time-domain Neal-Smith criterion,we perform the multi-objective optimization to obtain the optimal pilot reference models under different tasks;（4） we select the optimal pilot reference model according to the flight quality requirements and combine it with the aircraft equivalent model to form the man-vehicle closed loop reference model;（5） with the man-vehicle closed loop reference model,we design the aircraft flight control system by using the multi-objective optimization algorithm.Section 3 simulates the multi-objective optimization of the pilot reference model and the man-vehicle closed loop reference model;the simulation results,given in Figs.5 through 8,and their analysis show preliminarily that our multi-objective optimization algorithm can not only tune the parameters of the controller of the aircraft flight control system but also select the optimal pilot reference model under different tasks and use the optimization results to evaluate the PIO（pilot-induced oscillation） susceptibility.
