Abstract

This paper concerns with the generalized L-2 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 L-2 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.
