一种高超声速滑翔飞行器滑模控制器设计

A sliding mode controller design for hypersonic glide vehicle

针对高超声速滑翔飞行器(HGV)再入段姿态控制,设计了一种基于快速幂次趋近律的滑模控制器,通过仿真验证了该控制器的控制性能.仿真结果表明,该控制器能够实现对姿态角阶跃指令的良好跟踪,对参数偏差具有较好的鲁棒性,且在相同的飞行条件和控制器参数下,与基于传统幂次趋近律的滑模控制器相比具有更好的控制性能.

This paper designs a sliding mode controller based on fast power approach law for the attitude control of a hypersonic glide vehicle in reentry flight,and verifies the control performance of the controller by simulation.The simulation results demonstrate that the proposed controller achieves good tracking control for a step command of attitude angles,and has good robustness to parameter deviation,and that under the same flight conditions and controller parameters,this controller has better control performance than the sliding mode controller based on the traditional power approach law.
