摘要: 一、引言 众所周知,在具有纵向阻尼(增稳)系统的飞行操纵系统中,引入清洗网络的目的,是在增加等效飞机动稳定性的同时不要较大地削弱操纵性。所以正确地选择系统中的增益和清洗网络时间常数τ是很重要

Abstract: This paper, presents a calculation Method of Powell optimization under certain constraints, which is specifically made and designed by authors. Then authors suggest a practical .. method which .. optimizes two parameters, a gain K and a time constant of washout. networkm In the damped (stability augmented) system (containing nonlinear links) of aircrafts by means of Powell optimization method according to level quality requirement . for MIL-F-8785C specifications under stick shift at sinusoidal signal input and aircraft fuselage . being instantly subjected to impulse wind.
