Controllability and stability of a second-order hyperbolic system with collocated sensor/actuator

  title={Controllability and stability of a second-order hyperbolic system with collocated sensor/actuator},
  author={Bao-Zhu Guo and Yue-Hu Luo},
  journal={Systems & Control Letters},
A second-order hyperbolic system with collocated sensor=actuator is considered. The semigroup generation is shown for the closed-loop system under the feedback of a generic unbounded observation operator. The equivalence between the exponential stability of the closed-loop system and exact controllability of the open-loop system is established in the general framework of well-posed linear systems. Finally, the conditions are weakened for the diagonal semigroups with 6nite dimensional inputs… CONTINUE READING
