Coordinated Control Technology of Air-to-Air Missile with Lateral Jets and Aerodynamic Fins

通过构建侧向射流与气动舵复合控制弹体的混杂系统动态模型,并推导离散射流信号的Fourier级数,分析了调制脉冲近似阶次对弹体操纵特性的影响,建立了侧向射流装置的连续性模型。基于线性二次型优化理论,并利用有效集算法,对导弹控制器及动态分配算法进行了联合设计。仿真结果表明,导弹对高频射流具有利于线性控制设计的低通滤波特性,所设计的最优控制器与动态分配算法能够充分利用不同类操纵机构的动态特性差异,实现对复合控制系统品质的综合优化。

By constructing a dynamical model of hybrid system referring to the missile controlled by lateral jets and aerodynamic fins and expanding the Fourier series of discrete jets,the impact of modulated pulse approximation orders on missile response is analysed,and a continuous model is developed for lateral jets actuator. Based on linear quadratic optimal theory and active sets algorithms,a collaborative design is completed for missile controller and dynamical allocation. The simulation results demonstrate that,for high frequency jet,missile poses low-pass filter characteristics allowing the following linear control design,and the proposed optimal controller with dynamical allocation algorithms is capable of making the best of dynamic differences of different actuators to achieve an integrated optimization of compounded control system performance.
