【摘要】 本文从5个方面对新一代可重复使用天地往返飞行器(reusablelaunchvehicle,RLV)中存在的多输入控制问题进行了讨论:1)RLV增加冗余输入通道后,对飞行器系统性能的影响;2)RLV存在冗余输入通道时的控制分配问题;3)RLV再入大气层时,舵面和喷流反作用系统(reaction-jet control system,RCS)异类执行机构的复合控制问题;4)RLV三通道关联耦合效应对控制的影响;5)RLV为抑制机体弹性振动而面临的执行器位置寻优问题.开展RLV多输入控制课题的研究,不仅能挖掘出控制科学中的新问题,推动控制理论的进一步发展,而且也能为工程实践提供重要的理论支撑.更多还原

【Abstract】 This article discusses the multiple-input problem in control of the reusable launch vehicle(RLV) in five aspects: 1) the effects of redundant control inputs on the performance index of the RLV’s system; 2) the control allocation for redundant input channels of the RLV; 3) blending aerodynamic surfaces with reaction-jet control system(RCS) in RLV’s reentry phase; 4) coupling effects on the control of the RLV; 5) location optimization of actuators for suppressing the elastic vibration of the airframe of the RLV. Research on the multiple-input problem in control of the RLV not only helps solving the essential problem in control theory and developing in this field, but also provides important theoretical support for engineering practice.更多还原
