Abstract

In this paper, the mixed Input Covariance Constraint (ICC) and H control problem is addressed for continuous-time polytopic Linear Parameter-Varying (LPV) systems with one-dimensional scheduling parameter. The upper bound of trace of the output covariance matrix is minimized subject to given constraints on input covariance matrix and H performance bound. This control problem is an extension of the mixed H2/H LPV control problem, and the resulting gain-scheduling controller guarantees not only closed-loop sys- tem robustness in terms of H norm bound but also output covariance performance over the entire scheduling parameter space. This problem can be efficiently solved by convex optimization of Parametric Linear Matrix Inequalities (PLMIs). This paper presents the characterization of control synthesis PLMI conditions to obtain the optimal state-feedback gain-scheduling controller satisfying both ICC and H constraints, and the application of developed synthesis conditions to a blended-wing-body airplane model for wing vibration suppression.
