Abstract
The paper introduces complemental explanation and analysis of existing time-delay identification scheme of nonlinear systems; meanwhile, points out the impropriety of NARMA model correction strategy for time-delay system^. The neural networks predictive control of time-delay system is taken as an example to present the correct NARMA model correction methods. Simulation results verify that the advanced correction methods can obtain good control performance and anti-disturbance capability.
