Time-Discretization of Nonlinear systems with Time Delayed Output via Taylor Series

摘要

The output delay is always existent in the 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 digital computer. In this paper a new method for the discretization of nonlinear systems using Taylor series expansion and the zero-order hold assumption is proposed. This method is applied to the sampled-data representation of a nonlinear system with constant output time-delay. A performance of the proposed method is evaluated using a nonlinear system with time-delay output.
