H∞ Control For Vehicle Active Suspension Systems In Finite Frequency Domain

Abstract

This paper considered the H∞ control problem for active vehicle suspension systems over a finite frequency domain. The H∞ performance is analyzed to measure the ride comfort of the vehicle. Based on the generalized Kalman_Yacubovich_Popov(GKYP) Lemma. To improve the ride comfort, the H∞ norm is decreased in specific frequency band. Our theoretical methods are formulated as a linear matrix inequalities(LMIS). The theoretical results are illustrated as simulation results to show the effectiveness of the proposed method.
