Weidong Jin · Control theory & applications · 1993
In course of the simulation of a linear time-invariant system, T is the calculating step of the state variabies, and the system output is usually calculated at intervals of AT. Using polynomial interpolating function to approximate the, system input and introducing the result obtained with augmented matrix algorithm, a fast simulation algorithm based on discrete analog method is presented in this paper. When N is large, the algorithm has much smaller computing amount than other similar algorithm.
