| 摘 要： | 在理解飞机飞行品质规范MIL-STD-1797A基础上，采用等铲系统准则评价了某机的俯仰轴飞行品质，等效系统是通过阻尼最小二乘法拟配获得，其拟配结果与人-机闭环操纵模拟试验结果一致，表明所采用的理论计算和模拟试验方法来验证飞行品质是可行的，合理的，此外，还探讨了等效系统模型形式，拟配参数初值的选取等对拟配结果的影响。

| Abstract: | The handing qualities of aircraft for pitch axis are assessed using equivalent system criteria based on the flying qualities specifications(MIL STD 1797A).The equivalent systems are obtained by the damped least square. The matched results are consistent with pilot aircraft system simulation. It shows that the suggested method of calculation and simulation is reasonable and feasible. In addition,the combined influence of the form of equivalent system model and choice of initial values on the matched results is also discussed. |
