transfer in control engineering. The rapid development of control technology has
an impact on all areas of the control discipline. New theory, new controllers,
actuators, sensors, new industrial processes, computer methods, new applications,
new philosophies…, new challenges. Much of this development work resides in
industrial reports, feasibility study papers and the reports of advanced collabora-
tive projects. The series offers an opportunity for researchers to present an

and rapid dissemination.
Solar energy collectors are rapidly becoming a common sight in the fabric of
urban infrastructure. Many domestic homes are now graced with either water-
basedheat-transferpanelsorphotovoltaicsolarpanelsontheirrooftops.Inparallel
with these myriad small-scale developments, there are proposals and installations
alreadyactivefortheindustrial-scaleharvestingofsolarenergy.Indeed,toensure
asignificantcontributiontotherenewableenergymixandtoenablethegeneration
of useful amounts of electrical power, industrial-scale plants are essential.
There are two main process architectures for large-scale thermal solar-energy-
capturesystems;eitherlocallyfocusedradiantsolarenergyistransferredtoaheat-
transfer fluid as in the ‘‘parabolic trough’’ process or the solar radiant energy is
globally focused onto a central heat transfer mechanism as in a central (tower)
receiver system. It is the parabolic trough process used in a distributed-collector
solar field (DCSF) plant that is of interest in this monograph Control of Solar
Energy Collector Systems by authors Jo?o M. Lemos, Rui Neves-Silva and José
M. Igreja.
ProfessorLemosandhiscolleaguesopentheirmonographwithanintroductory
chapter that briefly reviews thermal solar plants before focusing on DCSF plants
and their control. This opening chapter also includes a brief review of the control
literature for these plants and a discussion of the organisation of the monograph,
both of which are very helpful to the reader.
A key feature of this type of plant is that it is a distributed-parameter system
withspatiallydependentvariables,subjecttomodeluncertaintyandvarioustypes

of processes from industry and elsewhere that belong to this class of systems.
These include moisture control, traffic-highway control, glass-tube manufacture,

of interest to a wider readership than one simply interested in solar energy
collector control.
This monograph is a valuable contribution to the literature on solar-energy-
collector-plant control. The theory and experimental results presented also dem-
