A Multivariable Parameter Space Approach Applicableto Engineering Design of Autopilot of BTT Missile

研究了一类线性多变量参数不确定系统的参数空间方法及在导弹倾斜转弯自动驾驶仪设计中的应用问题。提出了一种新的使反馈增益阵Ｋ极小化的优化算法，方法简单实用。最后以ＥＭＲＡＡＴ导弹为例，用提出的多变量参数空间方法完成了导弹倾斜转弯自动驾驶仪设计。计算结果表明设计是成功的。

In my opinion, the approach of Arzelier et al is still somewhat deficient when applied to engineering design. My approach is different and the research work I did was demonstrated to be practical because it could achieve a robust design for the autopilot of US EMRAAT missile now undergoing development. I improved on Arzelier′s approach to the design of a class of linear multivariable uncertain system chiefly in that a different performance index, eq.(10), was proposed. Eq.(10) made it possible to make control matrix K both minimal and unique. Mathematical model for EMRAAT was taken from Ref.. With this model and eqs.(1) through (10), I calculated the minimal value of control matrix K as given in eq.(11). Poles determined from eq.(11) were: for α=0°, λ =-5.079±j0.97 and λ = -35.3±j6.90; for α=10°, λ=-5.32, -8.82 and λ =-34.1±j21.7. These pole values show that our approach could give a robust design for autopilot of EMRAAT missile.
