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 functions 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.

Multivariable adaptive feedforward control of a process having inputs and a process result output, in which the process is subjected to response transients due to process disturbances, wherein feedforward adaptation is accomplished by the method comprising the steps of: a) detecting a beginning and ending of the response transients; b) characterizing the inputs and process result output during a response transient by moments which comprise time-weighted integrals performed on the process result output and inputs; and c) relating the characterized inputs and process result output in general transfer function model equations to generate transfer function parameters relating the inputs to the process result output.
