Estimator-based control of transition in plane channel flows using various covariance matrices

Abstract

Control of transition in plane channel flows can be achieved by applying linear control to a suitable reduced-order system of state equations, with an appropriate state estimator. In the present work, a comparative study of various estimatorbased controllers has been carried out. The state estimators have been designed as Kalman filters using various covariance matrices. The performance of linear optimal controllers based on these estimators has been studied by numerical integrations. © 2006 Springer.
