Adaptive optimizer based on the sequential simplex method applied to the control of a thermo-mechanical pulping screening room
(2004)An adaptive optimizer is designed for control of multi-variable processes where the operating characteristics of the plant are time varying. Based on the original sequential method for static applications, the modified ... -
Advances in recycle mill supervisory control at Avenor Thunder Bay
(1998)This study examined supervisory control systems at Avenor Inc. Recycle Pulp Mill Thunder Bay making improvements in process control and automation. Supervisory controls were implemented for improving the control of a ... -
Co-firing of lignite with peat and white pine in a pilot scale bubbling fluidized bed air - emissions and feedstock reactivity
(2010)The increasing awareness of the environmental impact of fossil fuels (mainly coal) combustion, which leads to high levels of CO 2 , NO x , SO 2 , mercury and particulate emissions, has motivated research for potential ... -
Frequency domain tuning approach for adaptive feedforward controllers
(2003)Feedforward control provides a means for compensating measurable disturbances before the process output is affected. A novel tuning strategy for tuning feedforward controllers in frequency domain is developed in this ... -
Modeling and control of various styles of paper machine headboxes
(2003)In this thesis non-linear mathematical models of a typical paper machine approach system with three different styles of headboxes are presented. The non-linear models include the dynamics of the fan pump, DC motor, ... -
On-line optimization of thermomechanical pulping rejects screen using modified sequential simplex method
(2003)The sequential simplex method (SSM) was blended with the Nelder and Mead method to create two separate simplex methods. The first method is the Equilateral Optimum Following Simplex (EOFS). In this method, the simplex ... -
Production of bio-crude from forestry waste by hydro-liquefaction in sub-/super-critical methanol and upgrading of bio-crude by hydro-treating
(2009)Bio-energy is renewable and clean (with trace amount of sulfur and neutral in terms of CO2 emission), and abundant in resource, thus it could be a securable and sustainable energy for future. Due to the declining reserve ...
