Abstract
In this paper, the selection of H∞ weighting functions for general practical applications is investigated. Uncertainty weighting functions for typical low-order plants with parametric uncertainties are derived. It is shown that H∞ weighting function for a general SISO plant can be obtained by the combination of these elementary low-order plants. Weighting functions of reflecting other system specifications in H∞ design are also investigated. Explicit weighting function expressions are given to address position and rate limits of an actuator, tracking error performance, overshoot, etc. Finally, the proposed methods are demonstrated by the roll-angle control design of a laboratory-scale model of a vertical take-off aircraft via simulation and real-time control
