Multivariable adaptive feedforward control may be accomplished by detecting the beginning and ending of load transients, characterizing the inputs and process result during the transient by moments, and relating the characterized inputs and process result in a general transfer function model to generate transfer functions relating the input to the output. The transfer function coefficients are refined with successive disturbances by projecting from the current solution to the nearest point in an updated solution space. The transfer function coefficients of the selected solution are then used in compensators acting on the feedforward inputs to adjust a process control output to counteract the anticipated effects of the inputs.
