Abstract: This paper presents a new identification method for obtaining parametric state-space models for radiation force computation. These state-space models can substitute the convolution integral in the equations of motion based on the impulse response function method. Thus, the method converts the integro-differential equation to an ordinary differential equation which reduces the computational effort of radiation force computation significantly. The identification is performed in time-domain which means that the retardation function is subject to fit. The method is verified by the application to a floating cylinder.
