基于回馈递推的可变翼高超声速飞行器智能非线性控制
Intelligent nonlinear control for the hypersonic morphing vehicle based on the backstepping method
摘要
Abstract
In this paper, an intelligence nonlinear control scheme is proposed based on the backstepping method to solve the difficulty of the stable tracking control of the hypersonic morphing vehicle, considering compound disturb⁃ances as well as the influence of model uncertainties and unknown outside disturbances. First, the aerodynamic pa⁃rameters of the morphing vehicle are replaced with a curve⁃fitted approximation in order to build an accurate hyper⁃sonic model. Then, the feedback linearization approach is used to transform the nonlinear vehicle model into a strict feedback multi⁃input/multi⁃output nonlinear system. The nonlinear system is divided into three subsystems accord⁃ing to the features of the state variables and the virtual control signals are calculated for every subsystem. Next, the radial basis function ( RBF) is proved to have excellent capability in restraining unknown disturbances, and a dy⁃namic surface control strategy is employed to eliminate the explosion terms. The simulation results show that the pro⁃posed method can ensure the integral stability of the closed⁃loop system, as well as can have excellent tracing per⁃formance and robustness.关键词
