摘　　要：针对变体飞行器在不同的机体构型其控制目标不同,提出了一种基于平均驻留时间方法的切换线性变参数(switching linear parameter varying,SLPV)鲁棒H_∞控制方法。该方法根据变体飞行器的任务模式及性能指标要求把后掠角变化范围分成不同的区域,在不同的区域根据相应的控制目标给出系统满足鲁棒H_∞控制性能指标可解的条件及相应的LPV(LPV modeling of morphing aircraft)控制器,并用平均驻留时间方法保证变体过程的稳定性。仿真结果表明飞行器在变体过程中具有良好的鲁棒性和操纵性能。A morphing aircraft has different control objectives in different configurations. For the multi-objectivecontrol problem of the morphing aircraft,a robust controller of theswitchinglinear parameter varying（ SLPV） is proposed based on the average dwell time switching scheme in which the range of the sweep angle is divided into subregions according to the flight modes and design objectives,and the solvability condition of the problem with a given robust performance indices is established and a group of the LPV controllers is designed accordingly,meanwhile,the average dwell time scheme of switching is adopted to maintain the stability and the control performance of the aircraft in morphing. At last simulation results are used to showthat the designed controller can guarantee the excellent robustness and control performance.
