Controller design of high-speed vehicle based on dynamic inverse fractional-order PIλDμ
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.
