Static output feedback synthesis under an integral quadratic constraint with application to high capacity transport vehicles

This paper proposes a new linear matrix inequality (LMI) approach for H_∞ static output feedback synthesis under an integral quadratic constraint (IQC) on the states. The proposed approach is applicable to a wider class of systems if compared to the relevant previous work. The new sufficient LMI condition for the IQC constraint might also be preferable to work with when considering systems that have affine parameter dependence in the descriptor form. As a particularly relevant application, the proposed approach is then considered for the control of a high capacity transport vehicle to enhance its lateral performance. The verification results confirm significant reductions in rearward amplification of yaw rates and high speed transient offtracking for the nominal system.
