摘要：
A novel mathematical expression for time moments (TMs) of discrete time interval system is introduced in this paper. Based on these TMs, the model of DIS is also derived. For computing the lower-order model for DIS, modified integrated derivative (MID) technique along with matching of TMs are adopted. To demonstrate this technique, a DIS is exemplified through test systems. The simulated results are compared with various existing techniques to evaluate the accuracy of the proposed technique.
