摘要: Abstract In this paper, an improved identification algorithm is presented for continuous-time delay systems under unknown initial conditions and disturbances a wide range of input signals expressible as sequence step signals. It based on novel regression equation which derived by taking into account the nature underlying test signal. The has more linearly independent functions thus enables to identify full process model with time well combined effects condition disturbance without any iteration. Unlike method in Wang et al. [Q.-G. Wang, M. Liu, C.H. Chang, W. Tang, Robust from relay tests presence non-zero disturbance. Industrial Engineering Chemistry Research 45(12) (2006) 4063–4070], new requires no data before starts. Its effectiveness demonstrated through examples.
