This paper develops a sampled-data H∞ control strategy for attitude stabilization and vibration suppression of flexible spacecrafts. After introducing an impulsive observer-based sampled-data controller, the closed-loop system is built as a type of hybrid systems consisting a continuous-time and an impulsive differential system. Based on Lyapunov functional method, a sufficient condition is derived...
This paper investigates the missile attitude control problem. The model used in this paper is with respect to the Euler attitude angles and their derivatives which can be measured and computed easily. A robust practical finite-time control algorithm is proposed based on the terminal sliding mode approach. It is proved that all of the signals in the closed-loop system are bounded and the tracking error...
The finite-time tracking control for reusable launch vehicle with matched disturbance is investigated. An adaptive-multivariable controller is proposed where the bounds of the perturbations are not known. A proof of the finite-time convergence of the closed-loop system is derived using the Lyapunov technique. The feature of the proposed control scheme is that it does not require any information on...
