临近空间飞行器的鲁棒控制器设计

Robust Controller Design for Near Space Vehicle

采用H_∞混合灵敏度鲁棒控制方法设计系统纵向控制器,引入加权函数,由加权函数直接反映系统的各项性能指标,使被控对象具有较强的鲁棒性。仿真结果表明,在飞行器的整个飞行包线内,设计的H_∞混合灵敏度鲁棒控制器能够使飞行器的响应较快,系统具有较强的鲁棒性。

Use H_∞mixed sensitivity robust control method to design a system longitudinal controller to achieve strong robustness by introducing weighting function.The performance indexes of the system are directly expressed by the weighting function.Simulation results show that the controller can make the vehicle response faster in the entire envelope of the vehicle and the system has strong robustness.
