In this work, the control optimization of a rotary kiln located in a cement plant is described. The need to enhance the efficiency level, to increase the profitability as well as the commitment to meet precise production standards has motivated the adoption of Model Predictive Control techniques. The adopted system architecture is composed of two different optimization layers. A suitable interaction...
Home & Building Automation provides automatic control of indoor environments and its primary goals are the fulfillment of user requirements while realizing significant energy savings. In the present paper, energy saving in home and office buildings is achieved through an efficient management of heat and lighting devices and with the exploitation of renewable resources, like sun (thermal and light...
In this paper, a supervisory control system for oxygen consumption optimization on a syngas manufacturing process plant is proposed. A grey-box multivariable parametric identification of the oxygen compressor system is first performed. Consequently, by means of dynamic simulations the structure of an optimal control system has been determined, also reflecting the implementation constraints linked...
In this paper, we propose a methodology for marine archeological survey, which aims at enhancing productivity and safety during on-field missions. A primary interest of the archaeological investigation is to extract, in a non invasive way, as much information as possible from a site with minimal expenditure of time and of expensive resources. In general, this is done by taking photos and measurements...
In this paper hybrid automata have been used in order to identify the more suitable model of a gasification process, at the occurrence of variations of plant's operative conditions and specifications. From the identification process performed on historical series at disposal and from the model validation phase it was concluded that one single model was not sufficient to assure good predictions, especially...
In this paper a formalism which allows to describe the logics characterizing industrial discrete processes in a simple and intuitive way is described together with the tool developed for its actual implementation. The formalism, named PriSMa (Priority State Machine), is derived from the state diagrams concepts from which in particular inherits its graphical representation adding to these two main...
This paper summarizes the work done on the development of a module to interface a commercial mechanical scan sonar within an ROV control architecture and its integration with the other modules. The sonar module fulfills the scope of endowing the ROV with an open tool for the management of the sonar setting, adapting sonar performances to the specific mission requirement. In particular, this work is...
The objective of the low level control system of marine vehicles is to generate a desired thrust in the face of environmental disturbances and modelling uncertainties. The control objective of standard low level control solutions is the propeller angular speed that is assumed to be related to the produced thrust through a known hydrodynamic model. The presented approach differs from the above as the...
