Comments on 'Block multirate input-output model for sampled-data control systems'

摘要

In the above paper, Albertos (1990) presents a modeling technique to model linear, time-invariant systems with synchronous sampling. The model is derived from both the discrete transfer function and state-space representation of a given system and yields two similar expressions. Albertos equates the two in Lemma 2.1; there is, however, an inconsistency in Lemma 2.1, and this is discussed further.
