Frequency Domain Analysis and Flight Validation of Adaptive Augmentation Controller
The frequency domain analysis of the adaptive augmentation control for a launch vehicle is fo-cused in this paper.Firstly,the adaptive augmentation control framework is modified and considered as a single-input single-output block in order to simplify the frequency domain analysis.Furthermore,the fre-quency domain analysis of the controller is performed by linearizing the differential equation and using a simplified analytical solution,and then the frequency domain model is obtained.Finally,the adaptive augmentation controller is validated during the flight test on a reusable launch vehicle prototype.The result of flight data shows that the frequency model of adaptive augmentation controller is accurate and can a-chieve better control performance.
