On semi-global stabilizability of anti-stable systems by saturated linear feedback
Tóm tắt
It was recently established that a second-order anti-stable linear system can be semi-globally stabilized on its null controllable region by saturated linear feedback and a higher order linear system with two or more anti-stable poles can be semi-globally stabilized on its null controllable region by more general bounded feedback laws. We will show in this paper that a system with three real-valued anti-stable poles cannot be semi-globally stabilized on its null controllable region by the simple saturated linear feedback.
