    En este artículo, se propone el diseño de un experimento alternativo a la maniobra de zig-zag estándar para la estimación de parámetros de modelos de maniobra lineales de buques. En el diseño del experimento, se realiza la selección de la frecuencia de una señal de entrada mediante un enfoque basado en la sensibilidad de los parámetros. La estimación de los parámetros se efectua utilizando un metodo de error de predicción junto con el filtro de Kalman. Para la evaluación del experimento diseñado con el estimador propuesto y la validación del modelo obtenido se proponen dos casos de estudio: uno en simulación y otro con datos adquiridos en aguas abiertas.

    In this paper we propose an experiment design alternative to the standard zig-zag maneuver in order to estimate parameters of ship linear maneuvering models. In the experiment design is selected the frequency of an input signal using a sensitivity approach. The parameter estimation is performed using prediction error methods together with the Kalman filter. For the evaluation of the designed experiment with the proposed estimator and for the model validation, we propose two cases of study: one in simulation and another one with acquired data in open waters.
