  • Abstract
    In this paper, a mixed H2/H∞ controller is designed for 1/4 car suspension model. Neither H2 nor H∞ controllers can provide goals of active suspension separately (i.e. minimizing body vertical acceleration considering restriction on suspension displacement). So, in this paper both objectives are considered in a mixed H2/H∞ problem. The Riccati equations are solved using a recursive algorithm and the mixed H2/H∞ controller performance is compared with H2 and H∞ controllers through frequency and time domain simulations.
