| Abstract: | The rotation dynamic and quaternion kinetic equations of spacecraft were educed according to the principles of variable-structure control. The function relation between attitude angle speed and attitude angle was studied out with quadratic optimum method, and gained sliding plane, and variable-structure with sliding mode control system was designed. Theoretical analysis and simulation result shows that the transient and steady state performance of the control system is satisfactory, it has very good robustness to external disturbance and perturbation of system. |
