Abstract

This paper has developed an iterative model-based mixed H2/H∞ controller design method. This method cretes excellent disturbance rejection because of the H2 criterion, and a good performance and stability margin because of the H∞ criterion. In this paper, the design of the active suspension system has been attempted, where the main objective is to minimize the harmful vibration of the vehicle body caused by road irregularities. The purpose of the mixed performance criteria is to combine the traditional quadratic form with the H∞ norm of the body acceleration. The aim of this example has been to illustrate the fact that, if the design is performed on a nominal model in which the parameters are not exactly known, the iterative design is an important tool for practicing engineers. The research project is to be continued. In the future, several problems have yet to be investigated such as the convergence property of the iterative scheme, the balance between the H2 and the H∞, the tune of the parameters γ and the μ.
