Abstract
To obtain the response of sampled system better than of using the Zero Order Hold (ZOH) method. The approximation to the integral using Bilinear discretization is proposed. The results from simulation show that the obtained response from the bilinear or Tustin method is better than the ZOH method at the same sampling time. However, if another of descretization method is necessaries, the overall closed-loop system should be considered.
