Abstract

In this paper, we propose a method to design robust sliding hyperplanes in the presence of mismatched parametric uncertainty based on quadratic stability. The robust sliding hyperplane is constructed from a Riccati inequality associated with quadratic stabilizability. The proposed method enables us to deal with structured uncertainty and optimize the sliding motion by applying the guaranteed cost control idea.
