Resumen
This paper presents a novel identification method for non-minimum phase systems based on the step response. The proposed approach provides a linear second-order model approximation avoiding complex experimental design. The proposed method is a closed identification algorithm based on characteristic points of the second order non minimum phase system step response. It is validated using different linear models. They have inverse response between 3,5% and 38% of the final steady state response. In simulations, it has been shown that satisfactory results can be obtained using the proposed identification procedure, where the identified parameters present mean relative errors lower than those obtained by Balaguer’s method.
