Robust Analysis of Vehicle Suspension System Uncertainty

摘要

The paper presents the systematic approaches toward robust stability analysis of H{sub}2/H{sub}∞ controlled active suspension systems. The computational algorithms for the structured singular value μ are the main features of the work with an emphasis on quantifying the effects of uncertainty of the systems. The representation of vehicle parameter uncertainties is given in detail. The robustness test is subsequently done based on a quarter vehicle model. The results have showed that the H{sub}∞ controller is the best one on both robust stability and robust performance.
