Abstract
In this work, by utilizing a disturbance observer-based control (DOBC) method, the resilient tracking control is studied for the unmanned aerial helicopter (UAH) with paramteter uncertainty, multiple disturbances, and input perturbation. Firstly, a state observer and two disturbance observers are respectively constructed to estimate the unmeasurable flapping motion states and outside disturbances, which are further utilized to design the feedforward controller. Secondly, by considering stochastic perturbation, a resilient feedback controller is proposed and an overall closed-loop error system is established. Thirdly, based on stochastic control theory and robust control method, a sufficient condition is obtained to guarantee the asymptotical stability and H∞ performance index for the closed-loop error system. Furthermore, the observer gains and controller one can be jointly checked by solving the derived linear matrix inequality (LMI). Finally, some simulations are presented to verify the effectiveness of the derived control method.
