摘　　要：针对超空泡航行体纵平面运动时受到的强非线性滑行力以及存在外界干扰的问题,提出了一种H_(2)/H_(∞)状态反馈鲁棒控制方法。首先,利用线性变参数(linear parameter variyng,LPV)的方法将航行体模型转换成LPV镇定模型;其次,将LPV镇定模型转换成LPV跟踪模型,在考虑外界干扰的情况下,设计了H_(2)/H_(∞)状态反馈鲁棒控制器;最后进行仿真分析,结果表明,所设计的控制器能够使系统快速、准确地跟踪期望值,同时对外界干扰具有良好的抑制作用。A H_(2)/H_(∞)state feedback robust control method is proposed to solve the problem of strong nonlinear sliding force and external interference in the longitudinal plane motion of a supercavitating vehicle.Firstly,the reference control model of the vehicle was selected,and the linear parameter variyng(LPV)method was used to convert the model into LPV stabilizing model.Secondly,LPV stabilization model was transformed into LPV tracking model.Then,the H_(2)/H_(∞)state feedback robust controller was designed in the case of external interference.Finally,the simulation results show that the designed controller can track the expected value of the system quickly and accurately,and has a good inhibitory effect on the external interference.
