摘要
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．
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.
