Abstract

This paper proposes a system identification method for single-input single-output linear time invariant continuous systems only using one-shot closed-loop transient data. The method consists of two methods based on an integral-equation and a direct least-squares approach, respectively, and the former is used as a preprocessing step for the latter. The validity of our proposed method is shown by numerical examples in which the continuous-time transfer functions of a non-minimum phase plant and an unstable plant are identified with the method and their evaluation is achieved.
