英文摘要 | The problem of assigning all poles of a closed-loop system in a specific disk by dynamic output feedback is considered for discrete systems with multiple time delays which are not exact integer multiples of the sampling interval. This kind of pole assignment problem is named D-pole placement, and its relation to robustness properties is discussed. Thus, the robust D-ple placement is subsequently proposed and a robust delay-dependent criterion is derived to ensure D-stability of the discrete multiple time-delay systems subject to parametric uncertainties. Furthermore, with this robust criterion, the bounds can also be estimated for allowable parametric uncertainties that guarantee all poles of the discrete uncertain multiple time-delay systems to remain inside the specified disk. Finally, an example is given to illustrate our results. |
