导弹高机动性和垂直发射的必要性引起了人们的兴趣,即,在大迎角飞行状态下有效的非常规控制设计技术。对于大多数导弹配置,需要采用推力矢量控制和常规气动控制。研究了具有气动和推力矢量控制的地空导弹的非线性建模、动力学分析。该导弹的气动力和力矩模型包括具有挑战性的大攻角气动特性和所谓的混合控制,即,利用尾翼和喷气翼作为控制面。在飞行包线内对推力矢量和气动控制效果进行了分析。不同的自动驾驶仪设计是通过混合控制完成的。在包括机动目标在内的目标集上实现了中段和末段制导算法。提出了一种不同的初始翻转策略,并与标准滑行转弯策略进行了比较。比较了气动和推力矢量控制下的初始翻转策略。在此基础上,采用实数编码遗传算法研究了一些关键机动和混合控制比。实现了低空目标的快速翻转、混合控制比拦截机动分析和拦截初机动优化。

 

The recent interests in the necessity ofhigh maneuverability and vertical launching triggered namely the unconventionalcontrol design techniques that are effective at high angle of attack flightregimes. For most of missile configurations, this interest required thrustvector control together with conventional aerodynamic control. In this study,nonlinear modeling and dynamical analysis of a surface to air missile with bothaerodynamic and thrust vector control is investigated. Aerodynamic force andmoment modeling of the presented missile includes the challenging high angle ofattack aerodynamics behavior and the so called hybrid control, which utilizesboth tail fins and jet vanes as control surfaces. Thrust vector and aerodynamiccontrol effectiveness is examined during flight envelope. Different autopilotdesigns are accomplished with hybrid control. Midcourse and terminal guidancealgorithms are implemented and performed on target sets including maneuverabletargets. A different initial turnover strategy is suggested and compared withstandard skid-to-turn maneuver. Comparisons of initial roll with aerodynamicand thrust vector control are examined. Afterwards, some critical maneuvers andhybrid control ratio is studied with a real coded genetic algorithm. Rapidturnover for low altitude targets, intercept maneuver analysis with hybridcontrol ratio and lastly, engagement initiation maneuver optimization isfulfilled.
