摘　　要：在采用MIL-1797-STD有人驾驶飞机飞行品质规范检验某第三代战斗机飞行品质过程中,在计算鹊克准则(即瞬时峰值比、上升时间及有效时间延迟)时,认为通过利用高阶系统传递函数求出的时间响应特性得出的结果比通过求解由飞机及控制系统组成的微分方程得出的结果更合理;在计算尼尔-史密斯准则时,提出了一种利用优化技术确定该准则的驾驶员参数kp和补偿τp1,τp2值的方法,取得了满意的效果。When checking a third generation fighter aircraft which is in service with MIL-1797-STD, it is thought that it is more reasonable to get the Chalk criteria(i.e. ratio of peak values, uprising time and time delay) with the time response curve obtaining through transferring function of a high order system, than time response curve obtaining through solving differential equations corresponding to the aircraft and its control system. One kind of methods to determine the values of parameters about pilot's k_p and compensation parameters τ_(p1),τ_(p2) of the Neal-Smith criteria with optimal technique is put forward in this paper and the method works very well.
