Stabilization of Chen-Lee system with uncertainty and external perturbation via UDE-based control method

The stabilization of Chen-Lee system with uncertainty and external perturbation is investigated in this paper. Firstly, a suitable filter is presented, by which the uncertainty and external perturbation can be estimated asymptotically. Secondly, two uncertainty and disturbance estimator (UDE)-based controllers are proposed and applied to realize the stabilization problem of such system. Finally, numerical simulation results verify the effectiveness and accuracy of the obtained results.
