초록 ▼

A method and apparatus for controlling a multiple-input, multiple-output (MIMO) system, such as a sheetmaking system, including identifying a decoupling gain matrix by comparing an actuator control vector against a measured output vector and processing an error vector to update the decoupling gain matrix. The dynamic components of one dynamic mode in the system are separated from that of other dynamic modes such that the input-output characteristic of the process may be treated as independent channels.

대표청구항 ▼

A method of controlling a sheetmaking process using an adaptive decoupling, multiple-input, multiple-output control system, comprising the steps of: applying to the system an actuator control signal; producing a process output signal by measuring an output of the process; identifying a decoupling gain matrix by: a) filtering the actuator control signal by a matrix filter representing uncoupled dynamics of the process to produce a filtered actuator control signal; b) decoupling the process output signal by multiplying it with an adjustable matrix representing inverted coupling of the system to produce a decoupled output signal; and c) adjusting the adjustable matrix so as to minimize a difference between the filtered actuator control signal and the decoupled output signal, thereby producing the decoupling gain matrix; comparing the output signal to a reference signal to produce an error signal for controlling sheet quality of the sheetmaking process; and applying the decoupling gain matrix to the error signal to produce the actuator control signal.
