Thickness determination of web product by mid-infrared wavelength scanning interferometry

Non-contacting caliper measurements of free-standing sheets detect mid-ir interferometric fringes created by the reflection of light from the top and bottom surfaces of the sheet. The technique includes directing a laser beam at a selected angle of incidence onto a single spot on the exposed outer surface and scanning the laser beam through a selected wavelength range as the laser beam is directed onto the exposed outer surface and measuring the intensity of an interference pattern that forms from the superposition of radiation that is reflected from the exposed outer surface and from the inner surface. ... Honeywell Limited

Method for on-line imaging of mesophase particles

On-line detection of mesophase particles employs a laser diode light source to illuminate a target area with a pulsed laser linearly or circularly polarized probe beam. Analysis of images determines extent of presence the birefringent mesophase particles, which are precursors to coking in catalytic hydrocracking processes. ... Honeywell Limited

Method of designing model predictive control for cross directional flat sheet manufacturing processes to guarantee spatial robustness and to prevent actuator picketing

Automated parameter tuning techniques for cross-directional model predictive control for paper-making under user-specified parametric uncertainties to reduce variability of the actuator and measurement profiles in the spatial domain is proposed. Decoupling properties of the spatial and temporal frequency components permit separate controller design and parameter tuning. ... Honeywell Limited

Method of designing model predictive control for cross directional flat sheet manufacturing processes to guarantee temporal robust stability and performance

Automated parameter tuning techniques for cross-directional model predictive control for paper-making under user-specified parametric uncertainties are developed. The cd-mpc design explicitly accounts for parametric model uncertainty while finding a value for the cd profile trajectory generation that minimizes the cd settling time of the measurement 2 sigma spread and does not exceed an overshoot limit for actuator 2 sigma spread. ... Honeywell Limited

Technique to improve paper machine cross-directional model predictive control performance by creating a measurement profile reference trajectory

Controlling a multiple-array, sheetmaking cross-directional process with a multivariable model predictive controller (mpc) employs a cost function incorporating a prediction horizon. The mpc provides a measurement profile target reference trajectory over the prediction horizon of the mpc cost function. ... Honeywell Limited

Model-plant mismatch detection with support vector machine for cross-directional process behavior monitoring

A method includes obtaining operating data associated with operation of a cross-directional industrial process controlled by at least one model-based process controller. The method also includes, during a training period, performing closed-loop model identification with a first portion of the operating data to identify multiple sets of first spatial and temporal models. ... Honeywell Limited

Closed-loop model parameter identification techniques for industrial model-based process controllers

A method includes obtaining closed-loop data associated with operation of an industrial process controller, where the industrial process controller is configured to control at least part of an industrial process using at least one model. The method also includes generating at least one noise model associated with the industrial process controller using at least some of the closed-loop data. ... Honeywell Limited

Model-plant mismatch detection using model parameter data clustering for paper machines or other systems

A method includes repeatedly identifying one or more values for one or more model parameters of at least one model associated with a process. The one or more values for the one or more model parameters are identified using data associated with the process. ... Honeywell Limited

Method for on-line imaging of mesophase particles

On-line detection of mesophase particles employs a laser diode light source to illuminate a target area with a pulsed laser linearly or circularly polarized probe beam. Analysis of images determines extent of presence the birefringent mesophase particles, which are precursors to coking in catalytic hydrocracking processes. ... Honeywell Limited

Eco mode ecs logic

An environmental control system (ecs) includes a controller; and a mode selector in communication with the controller and configured to select at least one of a plurality of modes. The mode is based on one of: number of occupants in an environment; activity of the occupants in the environment; destination of the environment; and performance of an engine that moves the environment. ... Honeywell Limited

Optimal closed-loop input design for identification of flat-sheet process models

Sheetmaking cross-directional (cd) control requires a sophisticated model-based controller whose operation requires an accurate model of process behavior, but due to the complexity of the process, identifying these process models is challenging. Current techniques rely on open-loop process experimentation. ... Honeywell Limited

Augmented reality of paper sheet with quality measurement information

Augmented reality techniques for monitoring and controlling continuous sheetmaking systems superimpose real-time sheet quality measurements onto images of the sheet and/or machine during production. A portable, hand-held computer device that is equipped with a camera, such as a tablet or smartphone, enables an operator to direct the device at the sheet along specific locations of the papermaking machine and view an indication of one or more quality measurements that are superimposed over the image of the paper. ... Honeywell Limited

Caliper sensor and method using mid-infrared interferometry

Non-contacting caliper measurements of free standing sheets such as porous polymer and paper detect mid-ir interferometric fringes created by the reflection of light from the top and bottom surfaces of the sheet. The technique includes directing a laser beam at a selected angle of incidence onto a single spot on the exposed outer surface wherein the laser beam comprises radiation having a wavelength in the 3-50 micron range and scanning the laser beam through a selected angle range as the laser beam is directed onto the exposed outer surface and measuring the intensity of an interference pattern that forms from the superposition of radiation that is reflected from the exposed outer surface and from the inner surface. ... Honeywell Limited

Holmium oxide glasses as calibration standards for near infrared moisture sensors

Near infrared moisture sensors using stable holmium oxide glass calibration standards that simulate different moistures levels in paper obviates problems associated with glass encased paper samples. Holmium oxide glass has a strong absorption at 1.93 microns which is close to absorption by paper. ... Honeywell Limited
