Multiobjective Robust Control of Flexible Structure with Observer

摘要

In this paper the multiobjective robust control method for the vibration control of flexible structure is studied. The parameter uncertainty of the system is formulated as a H{sub}∞ optimal problem and the state feedback H{sub}2/H{sub}∞ mixednorm control with pole placement constraint is solved by LMI (linear matrix inequalities). Robustness of observer to the parameters uncertainty of system matrix is also formulated as a H{sub}∞ optimal problem with pole placement constraints and solved by LML. Simulation results show that this controller design approach is robustness under large parameters perturbation.
