Robust identification of continuous systems with dead-time from step responses

TL;DR: The proposed method is detailed for a second-order plus dead-time model with one zero, which can approximate most practical industrial processes, covering monotonic or oscillatory dynamics of minimum-phase or non-minimum-phase processes.

Least squares parameter estimation of continuous-time ARX models from discrete-time data

TL;DR: It is shown that if the highest order derivative is selected with care, a least squares estimate will be accurate and this theoretical analysis is complemented by some numerical examples which provide further insight into the choice of derivative approximation.
