Mechatronic aeropendulum / Eniko T. Enikov in IEEE transactions on education, Vol. 55 N° 4 (Novembre 2012) 

Public ISBD [article]  in IEEE transactions on education > Vol. 55 N° 4 (Novembre 2012) . - pp. 538 - 545 Titre : Mechatronic aeropendulum : demonstration of linear and nonlinear feedback control principles with MATLAB/simulink real-time windows target Type de document : texte imprimé Auteurs : Eniko T. Enikov, Auteur ; Giampiero Campa, Auteur Année de publication : 2013 Article en page(s) : pp. 538 - 545 Note générale : Education Langues : Anglais (eng) Mots-clés : Feedback  linearization  Simulink  Linear  feedback  control  Real-time  control  Real-time  windows  target Résumé : This paper presents a low-cost hands-on experiment for a classical undergraduate controls course for non-electrical engineering majors. The setup consists of a small dc electrical motor attached to one of the ends of a light rod. The motor drives a 2-in propeller and allows the rod to swing. Angular position is measured by a potentiometer attached to the pivot point. A custom-designed circuit board produces the controlled voltage input to the motor. The target board is powered and communicates with the PC through its USB port using a virtual RS-232 port. A simple MATLAB/Simulink module has been created to read the pendulum angle and send a command signal to the motor. The module is based on Real-time Windows Target software, which allows a sampling rate of up to 200 Hz. Students are able to design and test classical PID and phase lead-lag controllers, as well as modern controllers, including state-space controller design combined with feedback linearization. A semester-long series of assignments is described that can be carried out without the need for a specialized laboratory or teaching assistants. The project was tested in a classical control systems design class of senior-level mechanical engineering students. Student feedback and survey data on the effectiveness of the modules are also presented.

A neural network based sensor validation scheme for heavy-duty diesel engines / Giampiero Campa in Transactions of the ASME . Journal of dynamic systems, measurement, and control, Vol. 130 N°2 (Mars/Avril 2008) 

Public ISBD [article]  in Transactions of the ASME . Journal of dynamic systems, measurement, and control > Vol. 130 N°2 (Mars/Avril 2008) . - 10 p. Titre : A neural network based sensor validation scheme for heavy-duty diesel engines Type de document : texte imprimé Auteurs : Giampiero Campa, Auteur ; Manoharan Thiagarajan, Auteur ; Mohan Krishnamurty, Auteur Année de publication : 2008 Article en page(s) : 10 p. Note générale : dynamic systems Langues : Anglais (eng) Mots-clés : sensors;  engines;  failure;  signals;  measurement;  roads;  diesel  engines;  approximation;  artificial  neural  networks Résumé : This paper presents the design of a complete sensor fault detection, isolation, and accommodation (SFDIA) scheme for heavy-duty diesel engines without physical redundancy in the sensor capabilities. The analytical redundancy in the available measurements is exploited by two different banks of neural approximators that are used for the identification of the nonlinear input/output relationships of the engine system. The first set of approximators is used to evaluate the residual signals needed for fault isolation. The second set is used—following the failure detection and isolation—to provide a replacement for the signal originating from the faulty sensor. The SFDIA scheme is explained with details, and its performance is evaluated through a set of simulations in which failures are injected on measured signals. The experimental data from this study have been acquired using a test vehicle appositely instrumented to measure several engine parameters. The measurements were performed on a specific set of routes, which included a combination of highway and city driving patterns.
