This paper describes a new method to obtain passive and stable state-space models for radiation force computation. These models can substitute the convolution integrals in the Cummins Equation and thus reduce the computational effort of radiation force calculation by about one magnitude. In contrast to existing substitution methods, there no longer exists a trade-off between accuracy, stability and passivity of the obtained model, which allows the highly accurate radiation force calculation of floating systems with multiple degrees-of-freedom.
