Abstract
In this paper, a new switched static output feedback controller design for uncertain linear time-invariant (LTI) systems is proposed. The approach chosen for the design of static output feedback gains is based on the two-stage method, which consists in first obtaining a state feedback gain matrix that is then used as an input parameter for the design of the desired static output feedback controller at the second stage. The proposed strategy considers performance improvement regarding the specification of a minimum closed-loop rate. The solution for the investigated problem is presented in terms of linear matrix inequalities (LMIs) obtained using the Finsler’s Lemma. The obtained results are compared with a robust static output feedback method, in a controller design and practical implementation for a real active suspension system.
