Authors: Rato, Luís; Salgueiro, Pedro; Lemos, João Miranda; Rijo, Manuel
Abstract: This paper concerns to the application of adaptive control to a large scale water canal experimental plant. Water canals are complex spatially distributed systems which aim at distributing water either for irrigating, or domestic, or industrial purposes.
In this paper a predictive adaptive control algorithm (MUSMAR) is
applied to a large scale experimental water canal prototype.
The experimental facilities with a fully instrumented canal, a PLC network and a SCADA system,
are briefly described. This paper describes the
developed software module and the MUSMAR control algorithm.
Finaly, Some
experimental results obtained in the
experimental water canal, are presented.2007-04-30T23:00:00ZM-Traffic - A Traffic Information and Monitoring System for Mobile DevicesRomão, TeresaRato, LuísFernandes, PedroAlexandre, NunoAlmada, AntãoCapeta, Nunohttp://hdl.handle.net/10174/14432009-04-07T14:38:06Z2006-04-30T23:00:00ZTitle: M-Traffic - A Traffic Information and Monitoring System for Mobile Devices
Authors: Romão, Teresa; Rato, Luís; Fernandes, Pedro; Alexandre, Nuno; Almada, Antão; Capeta, Nuno
Abstract: This paper presents Mobile Traffic (M-Traffic), a multiplat-
form online traffic information system, which provides real time traffic
information based on image processing, sensor’s data and traveller be-
haviour models. In order to estimate route delay and feed the optimal
routing algorithm a traffic microscopic simulation model is developed and
simulation results are presented. This mobile information service ubiqui-
tously provides users with traffic information regarding their needs and
preferences, according to an alert system, which allows a personalised
pre-definition of warning messages.2006-04-30T23:00:00ZKNOWLEDGE REPRESENTATION APPROACH TO CLOSED LOOP CONTROL SYSTEM - A TANK SYSTEM CASE-STUDYRato, LuísRodrigues, Irene PimentaGomes, Ruihttp://hdl.handle.net/10174/13732016-03-29T11:11:05Z2005-08-31T23:00:00ZTitle: KNOWLEDGE REPRESENTATION APPROACH TO CLOSED LOOP CONTROL SYSTEM - A TANK SYSTEM CASE-STUDY
Authors: Rato, Luís; Rodrigues, Irene Pimenta; Gomes, Rui
Abstract: Control engineering problems are dealt within a plethora of methods and approaches depending on the a priori
knowledge, the description of the process to control, and the main control goal. Classical control theory is
mainly based on properties of numerical models. This paper presents an approach that applies to a class of
processes described by numerical and logical relations using inference and a knowledge base system. To attain
this goal an ontology for control systems is constructed. The work presented in this paper is based in a three
tank system benchmark.2005-08-31T23:00:00ZPredictive Adaptive Control of water level in canal poolsLemos, João MirandaRato, LuísMachado, FernandoNogueira, NunoSalgueiro, PedroRijo, Manuelhttp://hdl.handle.net/10174/13722008-12-23T11:58:07Z2007-08-31T23:00:00ZTitle: Predictive Adaptive Control of water level in canal pools
Authors: Lemos, João Miranda; Rato, Luís; Machado, Fernando; Nogueira, Nuno; Salgueiro, Pedro; Rijo, Manuel
Abstract: A case study on the use of a predictive adaptive algorithm to control pool level in a pilot water distribuition
canal is described. The algorithm is a modification of the basic MUSMAR controller that includes parallel
integral action and, in the case of multiple pools, feedforward action to coordinate the gates. Experimental
results in the case of a single pool and simulations for multiple pools are presented. The contributions of the
paper stem from the explicitation of rules for tuning the adaptive controller in a practical situation and from the
coordination of different pools using reduced complexity controllers and feedforward in a multivariable setting2007-08-31T23:00:00Z
