This paper deals with a semi-active vehicle suspension design. A quarter-car model, which captures many features of a real car suspension, is considered in this study. H2-norm is used to quantify control objectives of ride comfort, ride safety as well as suspension deflection and control effort. To guarantee system performance against system parameter changes an LMI-based (Linear Matrix Inequality)...
This study concerns with the application of multi-objective H∞/GH2 preview control to a real quarter vehicle suspension system. To this goal both linear and nonlinear models of the test rig are derived, and a unified design framework for preview design schemes of LQG-preview and multi-objective preview is introduced. Simulations are carried out to compare both strategies. The study involves the inclusion...
This paper develops an LMI-based solution for output-feedback constrained H∞ control design, and considers it for active vehicle suspension system. A quarter car model, which captures many features of real structures, is used in this study. To take more general road disturbances than white noise into account in the design procedure, H∞ performance measure is used to judge ride comfort, ride safety...
