چکیده انگلیسی
This paper presents a disturbance rejection controller for air-breathing hypersonic vehicles (AHVs) based on the technique of nonlinear dynamic inverse (NDI). An observer is employed to estimate the lumped disturbance on the nominal dynamics of AHVs, such as the external disturbances introduced by the changeable flight environment and the unsteady scramjet operation. With the help of this observer, an effective NDI controller is proposed to suppress the negative effect of the lumped disturbance on output channels. Under the proposed control, the input-to-state stability of the closed-loop AHV system can be ensured if the observer gain matrix is properly selected. A simulation study on the disturbed AHV model is provided to illustrate the effectiveness of this disturbance rejection NDI control.
