The paper is concerned with the robust finite-time stabilization problem of quadrotors subject to inertia uncertainty and disturbances. The underlying stabilization problem consists of controller designs for position loop and attitude loop, both of which are carried out based on the terminal sliding mode control approach. First, a robust finite-time position controller is designed by considering the...
This paper addresses a difficult problem of designing a control approach with simple structure to perform attitude tracking maneuver for rigid satellites. The satellite is subject to external disturbance torque and uncertain inertia parameters. An observer-based estimation law is first proposed to reconstruct the uncertain dynamics. It is shown that such estimation can be achieved with zero estimation...
The paper studies the problem of control for the attitude of aerocrafts with uncertainties in the inertial parameters and uncertainties in pneumatic torque parameters based on the rigid-body dynamics. For both of attitude control and horizontal movement control, the H2/H∞ controllers are designed. A numerical example is given to show the validity of the designed controller and the better robustness...
