Abstract EN
The robust optimal attitude control problem for a flexible spacecraft is considered.
Two optimal sliding mode control laws that ensure the exponential convergence of the attitude control system are developed.
Integral sliding mode control (ISMC) is applied to combine the first-order sliding mode with optimal control and is used to control quaternion-based spacecraft attitude manoeuvres with external disturbances and an uncertainty inertia matrix.
For the optimal control part the state-dependent Riccati equation (SDRE) and optimal Lyapunov techniques are employed to solve the infinite-time nonlinear optimal control problem.
The second method of Lyapunov is used to guarantee the stability of the attitude control system under the action of the proposed control laws.
An example of multiaxial attitude manoeuvres is presented and simulation results are included to verify the usefulness of the developed controllers.
