Sampled Data Representation of Nonlinear State Delay System

Article Preview

Abstract:

A state time delay always exists in practical systems. Analysis of the delay phenomenon in a continuous time domain is sophisticated. It is appropriate to obtain its corresponding discrete time model for implementation via a digital computer. A new method for the discretization of nonlinear systems is proposed in this paper. This method is applied to the sampled data representation of a nonlinear system with constant state time delay. The proposed scheme provides a finite dimensional representation for nonlinear systems with state time delay enabling existing nonlinear controller design techniques to be applied to them. A performance of the proposed method is evaluated using a nonlinear system with state time delay.
