Abstract

The author examines the suitability of modeling discrete-time linear systems with a finite number of impulse response (FIR) coefficients. The FIR terms can be used to construct a model of plant transfer function. A theoretical basis for this concept is developed in the form of theorems that characterize sets of transfer functions by their FIR coefficients. To illustrate the modeling technique a feedback control system is designed from the FIR model of an example plant transfer function and simulated. The results of this simulation provide an indication of the accuracy of the FIR model.<>
有限脉冲响应建模精度的检验
本文研究了具有有限个脉冲响应系数的离散线性系统建模的适用性。FIR项可用于构造植物传递函数模型。这个概念的理论基础是以定理的形式发展起来的,这些定理通过传递函数的FIR系数来表征传递函数的集合。为了说明建模技术,设计了一个基于实例传递函数的FIR模型的反馈控制系统并进行了仿真。仿真结果表明了FIR模型的准确性。
