| 英文摘要 |
| This paper considers the finite-time control problem for stochastic Markovian jump system subject to partial information on transition probabilities. Firstly, the concepts of finite-time stochastic stability and stabilization for stochastic Markovian jump systems are defined. Secondly, with the aid of matrix transformations, mathematical expectation and Gronwall inequality, a practical criterion, under which the stochastic systems are finite-time stochastically stable, is given. After that, a sufficient condition for stochastic stabilization via state feedback is obtained. Considering that the state of the system in practical engineering is often with partial information, we develop a dynamic output feedback controller which ensures the stochastic system to be finite-time stochastically stabilizable. The testing condition for the existence of such a controller is proved. Finally, a numerical example is given to show the validity of the designed method. |
