A H-infinity-based control design methodology dedicated to active control of vehicle longitudinal oscillations

摘要

This paper deals with the problem of active damping of vehicle oscillations. A complete methodology based on an H{sub}∞ optimization is presented. Several dedicated analysis tools are used in order to analyze the behavior of the closed loop system. Two tuning parameters allow the design of a controller managing the compromise between performance (in terms of attenuation and limit cycles) and robustness. Finally, a prefilter is designed in order to improve the performances without changing the robustness properties and the controller complexity.
