System Identification of a Class of Second-Order Continuous System
Zhi Gang Jia, Xing Xuan Wang · Applied Mechanics and Materials · 2014
An identification method of a class of second-order continuous system is proposed. This method constructs a discrete-time identification model, forms a set of linear equations. The parameters can be obtained by least square method. Simulation results show that the method is effective for a class of second-order system, and is not only for step response but also for square wave signal.
