| 英文摘要 |
| For the switched system composed of
linear subsystems with time-delay, the synthesis of dynamic feedback
control and switching strategy is concerned with the optimization of
H-infinity performance. Combining with the proper transformation of
closed subsystem, an improved construction of Lyapunov-Krasovskii
functional preserving the continuity free from switching actions is
employed, and the delay-dependent criterion is established for the
existence of controllers and switching strategy. Based on the
technique of parameter transformation and matrix transformation,
the proposed criterion is then equivalently reformulated in term of linear matrix inequality
(LMI) from which the parameters of the functional and controllers are explicitly presented.
Finally, a numerical example is given to illustrate the proposed method. |
