The use of multifrequency forcings to control certain resonant triad interactions relevant to pattern formation in spatially extended, parametrically forced systems was investigated. The most important, damped, resonant modes were classified and the dependence of the corresponding resonant triad interactions on the forcing parameters was determined. The relative phase of the forcing terms was used to enhance or suppress the nonlinear interactions. The results of the experiment were applied on the Faraday waves.
