Active suspension design based on mixed uncertainty modelling

This paper proposes the mixed lì synthesis for active suspension problems. With this method, a robust compensator that achieves nominal performance and meets robust stability specifications can be designed. Moreover, both the real parametric and the complex uncertainties are treated together, which usually yields a less conservative compensator than the traditional robust methods. In this paper, the design strategy is applied for active suspension, which involves real parametric uncertainties. The results are compared with the traditional LQG, complex lì and mixed lì methods.
