Abstract :
This paper considers properties of zeros of sampled-data models for linear time delay systems. Two types of holds; a zero-order hold and a fractional-order hold are treated as a hold. The first order approximate expressions for the zeros with respect to a small sampling period are derived by focusing attention on a normal form of the continuous-time systems. Stability of the zeros of the sampled-data models is discussed. Examples are given to show the advantages of the obtained results.
