This paper concerns with the generalized L2 estimation of the disturbance applied to a vehicle steer wheel. The study is specially useful for active vehicle suspensions utilizing wheelbase preview information. To design an estimator to perform satisfactorily for a wide range of road irregularities and to care for system structured (parametric) uncertainties, a generalized L2 gain based scheme is proposed to design the estimator. The problem is formulated using LMI's and to ensure desired transient dynamics for the system, some pole location constraints are considered. To evaluate the effectiveness of the proposed controller it is compared with a Kalman estimator designed under similar conditions. The results demonstrate effectiveness of the proposed estimator. The half car model used in this study is described in section II, section II also describes the problem and gives the framework for the design, section III gives the LMI-based solution for problem. This section is followed by the design of above mentioned estimator. In addition, in this section for the sake of comparison, a Kalman estimator is also designed. In section IV some numerical simulation is carried out to compare both estimators and section V contains concluding remarks.
