A simple observer based controller for the stabilization of systems with two unstable poles plus time delay

This work considers the problem of the stabilization of linear time invariant systems with two unstable poles plus time delay. For this, we will proposed a simple observer based controller in order to stabilize the system. A robustness analysis with respect to the delay uncertainty is presented as well as numerical examples and electronic implementation of the proposed schema in order to illustrate the performance of the closed loop system.
