Abstract

This article explores a successive convex optimization method for solving a class of nonconvex programming problems subject to bilinear matrix inequality (BMI) constraints. In particular, many control issues can be boiled down to BMI problems, which are typically NP-hard. To get out of the predicament, we propose a more relaxed feasible set to approximate the original one, based on which a local optimization algorithm is developed and its convergence is analyzed. As a case of application, we consider static output-feedback control for uncertain systems with disturbances in restricted frequency intervals. In order to strengthen the disturbance-rejection capability over the given frequency range, we establish sufficient and necessary analysis conditions via the generalized Kalman-Yakubovich-Popov lemma, under which the homogeneous polynomially parameter-dependent technique is adopted to facilitate the design. Finally, several examples are given to demonstrate the efficiency of the results.
