초록 ▼

Multivariable adaptive feedforward control may be accomplished by detecting the beginning and ending of a process control disturbance response, characterizing the measured inputs and process output during the disturbance by moments, which comprise time-weighted integrals performed on the process result output and inputs when the disturbance is a measured disturbance, and relating the characterized inputs and process result output in known general transfer function model equations to generate transfer function parameters which are used to calculate the coefficients of feedforward additive or multiplicative compensators.

대표청구항 ▼

A method of automatically adjusting at least one control parameter of a feedforward controller used in a control system coupled to regulate a process having inputs and a result output in a closed loop of said control system, and having a measured variable signal responsive to a measurable process disturbance response to a disturbance of said process, comprising the steps of: a) detecting the beginning of the process disturbance response by sensing a significant change in either of the measured variable signal or the control parameter and then detecting the ending of a disturbance response; b) determining whether the disturbance is an unmeasured disturbance response; c) characterizing the inputs and process result output during a disturbance response by moments which comprise time-weighted integrals performed on the process result output and inputs; d) selecting a model equation if the disturbance is a measured disturbance; e) 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 when the disturbance is a measured disturbance; and f) adapting transfer function model equations to relate the characterized inputs and process result output to generate transfer function parameters relating the inputs to the process result output when the disturbance is an unmeasured disturbance; and g) adjusting said at least one control parameter.
