摘    要:应用滑模控制设计了一种可重复使用运载器(RLV)再入姿态控制器,该控制器应用双环的滑模控制方案,可以获得对角速度及角度的同时跟踪,并具有较好的鲁棒性和解耦性能。针对RLV再入姿态的动力面与反作用混合控制的特点,运用优化控制选择配置算法把控制力矩指令配置为末端受动器的控制指令,分别由动力面与反作用致动器来执行。再入姿态仿真验证了该方法的精度、鲁棒性以及解耦的跟踪性能及有效性。

关 键 词:可重复使用运载器  再入姿态  滑模控制  优化选择配置

Abstract:This paper develops a RLV reentry attitude control method by using the sliding mode control(SMC)theory.The controller utilizes double-loop SMC scheme and provides robust,de-coupled tracking of both the angular velocity and the shuttle orientation angles.And pointing to the hybrid controlling characteristic of the aerodynamic surfaces and reaction control system of the RLV,allocating the control torque commands into the actuators such as the aerodynamic surfaces and reaction control system by using the optim...
Keywords:reusable lauch vehicle  reentry attitude  sliding mode control  optimal allocation
