摘要
为提高高速再入飞行器的控制品质,开展了基于非线性动态逆解耦技术及分数阶PIλDμ(FOPID)的控制技术研究.首先,在时标分离的基础上,建立了飞行器高速无动力再入模型.在此基础上,设计了动态逆分数阶PIλDμ控制器进行了三通道解耦控制.仿真结果表明,相对于传统PID控制器,动态逆分数阶PIλDμ控制器具有超调量小、响应快、稳态误差小等优点,以及良好的控制品质和鲁棒性,有利于高速飞行器的稳定控制.
Abstract
In order to improve the control quality of the high-speed reentry vehicles,the research on the control technology based on the nonlinear dynamic inverse decoupling technique and fractional-order PIλDμ(FOPID)was carried out.Firstly,a high-speed un-powered re-entry model of the vehi-cle was established on the basis of time scale separation.On this basis,a dynamic inverse fraction-al-order PIλDμ controller was designed for three-channel decoupling control.The simulation results show that the dynamic inverse fractional-order PIλDμ controller has the advantages of small over-shoot,fast response,and small steady-state error relative to the traditional PID controller.The pro-posed method has a good control quality and a good robustness,which is conducive to the stable control of high-speed vehicle.
