Stabilization and Disturbance Rejection for Chen System via DE-Based Control Method

This paper investigates the stabilization problem of Chen system with unbounded external disturbances in two cases. Firstly, two suitable filters are proposed and used to asymptotically estimate the corresponding disturbances. Secondly, two disturbance estimation (DE)-based controllers are derived, by which the stabilization of Chen system is realized. Finally, computer simulation is applied to verify the effectiveness and validity of the theoretical results.
