N2 - This paper develops an LMI-based solution for the design of a discrete-time multi-objective preview controller, and considers it for an active vehicle suspension system. A quarter car model, which captures many features of real structures, is used in this study and hence the look-ahead preview control is considered. To provide ride comfort for a wide range of road irregularities, $H-infty$ norm is used as a comfort measure, while generalized $H-2$ is used to care for the constraints on suspension working space, tire deflection and actuator saturation. Moreover, to ensure desired stability margins for the feedback part of the system, pole location constraints are considered in the design. The effects of inclusion of preview information in control law on ride comfort, ride safety, working space and power requirements, for various road profiles, are examined. The results demonstrate the effectiveness of the preview-included multi-objective design to pure feedback scheme.
