Abstract:

The design problem of fuzzy guaranteed cost controller with pole placement constraints for aerospace vehicle’s re-entry attitude control is studied. The uncertain attitude dynamic system descriptor during ASV’s (aerospace vehicle’s) reentry phase based on T-S fuzzy model with parameter perturbation is considered firstly, then, the stabilization problems of attitude angles and angular velocity errors are researched, and combined with disk pole constraints, a condition for the existence of fuzzy guaranteed cost control law with pole placement constraints is derived.
