DESCRIPTION:Paper making is an energy intensive process: in 2006\, UK pape
 r makers used an average of 4\,060 kWh of primary energy to produce each o
 f 5.63 million tonnes of paper products\, which thus used 22\,857.8 GWh of
  energy. A paper machine is a very multivariable process and yet it is typ
 ically controlled using traditional single loop control strategies which h
 ave difficulty comprehending and compensating for the effect a number of v
 ariables may have on each paper quality variable. Consequently\, in normal
  operation many potentially useful control variables remain unused.\n\nThe
  seminar will address the question of how much energy saving benefit multi
 variable control technology can provide in paper making. Present indicatio
 ns are that at least a 20% reduction may be possible. The energy reduction
  delivered by two recently implemented APC systems on full scale commercia
 l paper machines in Australia and Canada will be reported. The objectives 
 of two recently initiated university-based research and development projec
 ts\, aimed at better understanding the potential for reducing energy use i
 n paper making\, will also be reviewed.\n\nPaul was born and grew up in th
 e Hutt Valley of New Zealand. He completed a BE (Chem) degree at the Unive
 rsity of Canterbury NZ while holding a Tasman Pulp & Paper Co student burs
 ary and he worked at Tasman (now owned by Norske Skog) after graduating. H
 e completed a PhD at Cambridge University in advanced control systems engi
 neering and then embarked upon an academic career in the UK and in NZ. Thr
 ough his NZ university positions he undertook a number of modelling\, simu
 lation and controller design projects in pulp & paper\, in electrical ener
 gy supply and demand\, and in a variety of other industry sectors. This wo
 rk led Paul into consulting engineering and for 12 of the next 16 years he
  was responsible for launching performance improvement initiatives in indu
 stries world-wide\, using multivariable modelling and advanced process con
 trol. He and the engineers he has worked with in various companies are all
  currently employed by Perceptive Engineering\, based a little south of Ma
 nchester in the UK. More recently he has reduced his industry involvement 
 to allow time to take up part time positions in the Cambridge University E
 ngineering Dept (where he is a Senior Research Fellow) and in the School o
 f Engineering and Computer Science at Victoria University of Wellington (w
 here he is Professor of Control Systems Engineering).
