变结构自适应控制在BTT导弹中的应用

THE APPLICATION OF VARIABLE STRUCTURE MODEL REFERENCE ADAPTIIVE CONTROL FOR BANK-TO-TURN MISSILES

提出了ＢＴＴ导弹自动驾驶仪的变结构自适应设计方法。该方法完全基于对象参数变化和随机扰动的上下界，无需对系统进行参数辩识和对随机扰动进行在线估计，增强了控制系统的适应性和鲁棒性。在考虑了各种非理想因素的情况下，得到了令人满意的仿真结果。

new variable structure model referenee adaptive control method is proposed for bank-to-turn (BTT)missiles’roll channel autopilot designs.The method is completely based on the maximums and the minimums of plant’s parameter variations and random disturbances,and avoids utilizing on-line parameter identification and on-line random disturbance estimation,which improves the adaptivity and robustness of control systems.With many non-ideal factors taken into account,satisfactory digital simulation results are presented.
