基于δ-算子的采样控制系统的鲁棒稳定界

采样控制系统的扰动往往是连续时间系统参数的不确定因素通过离散化或采样的表现．研究连续时间系统参数扰动对δ－算子描述的采样控制系统参数的影响，建立了使δ－算子描述的扰动离散时间系统稳定所需满足的条件．利用该条件给出了使采样控制系统鲁棒稳定的连续系统参数的扰动界限

Robust Stability Bounds for Sampled-Data Control Systems of a Delta-Operator-Based Model

It was studied that the robust stability of sampled data systems of a Delta operator based model is subjected to parameter perturbations of continue time systems. The process by which the parameter perturbations in the underlying continue time model are propagated into the discrete time one was examined, and the upper bounds on these induced perturbations were proposed. The robust stability bounds for discrete time systems of Delta operator based model were derived. Combining the above findings yields the robust stability bounds on the underlying continues time perturbations.
