Το θέμα με το οποίο ασχολείται η παρούσα διπλωματική εργασία είναι ο έλεγχος τεχνητής καρδιάς. Πολλοί ερευνητές έχουν ασχοληθεί, από τη δεκαετία του 1950 ακόμα, με την μηχανική υποβοήθηση της κυκλοφορίας του αίματος. Τα τελευταία 10 χρόνια μάλιστα, η έρευνα έχει περάσει στο στάδιο της εφαρμογής σε ασθενείς που πάσχουν από σοβαρής μορφής καρδιοπάθεια. Η παρούσα εργασία ασχολείται, αρχικά, με την παρουσίαση της τεχνολογίας της μηχανικής υποβοήθησης της κυκλοφορίας που έχει αναπτυχθεί τα τελευταία 60 χρόνια. Έπειτα, παρουσιάζονται διάφορα μαθηματικά μοντέλα που έχουν προταθεί κατά καιρούς, τα οποία περιγράφουν το σύστημα της τεχνητής καρδιάς και παράλληλα παρουσιάζονται και τεχνικές ελέγχου οι οποίες καθιστούν το εκάστοτε μοντέλο λειτουργικό. Το μοντέλο που επιλέχθηκε, τελικά, στην παρούσα εργασία, περιγράφει την εξάρτηση του καρδιακού ρυθμού από την ένταση άσκησης σε κυλιόμενο διάδρομο τρεξίματος. Σκοπός της εργασίας είναι η προσαρμογή του μοντέλου στις απαιτήσεις της τεχνητής καρδιάς και ο έλεγχός του ώστε να παρουσιάζει την επιθυμητή απόκριση σε διάφορες εντάσεις άσκησης. / The subject of the present diploma thesis is control of an artificial heart. Many researchers have studied, even from the 1950’s, mechanical support of blood circulation. The last 10 years, research gave birth to applications that have been tested on patients suffering from congestive heart failure. As an introduction, we present the technology of mechanical support of blood circulation that has been developed over the last 60 years. We also present some mathematical models describing the artificial heart system with a reference to the control techniques that make each model functional. The model chosen for the present diploma thesis describes the heart rate response to exercise on a treadmill system. The target of this research is to adapt the chosen model to artificial heart specifications and to control the system so that it presents the desired response to a wide range of exercise intensities.

Bakgrund: Hjärtsvikt är idag en av våra folksjukdomar och tros öka i framtiden. Det är ett kroniskt tillstånd som karaktäriseras av flera olika symtom så som dyspné och andfåddhet. Den vanligaste orsaken till hjärtsvikt är ischemisk hjärtsjukdom som utgör 50-75% av all hjärtsvikt. New York Heart Association Functional Classification är en funktionsklassificering som är baserat på patientens egna upplevelser av sjukdomen och är graderad från I-IV. Att lida av en kronisk sjukdom kan innebära flera olika former av lidande som till exempel sjukdoms-, livs- och vårdlidande. Syfte: Att beskriva patienters upplevelser av hur hjärtsvikt och dess symtom påverkar det dagliga livet. Metod: Litteraturbaserad studie som är grundad på elva vetenskapliga artiklar. Resultat: Hjärtsvikt påverkar hela människan både psykiskt och fysiskt i det dagliga livet. Livet blir begränsat på grund av de somatiska symtomen där även emotionella svårigheter blir tydliga. Att inte längre kunna utföra dagliga rutiner och delta i aktiviteter leder till en känsla av isolering och försämrad livskvalité. Slutsats: Hjärtsvikt har en tydlig påverkan i patientens dagliga liv där kroppen konstant är under förändring. Detta leder till en okänd upplevelse där framtiden för patienten är oförutsägbar. Hjärtsvikt är ett tillstånd där hela människan bör beaktas för att kunna lindra lidande. / Background: Heart failure is currently one of the major diseases and is believed to increase in the future. It is a chronic condition characterized by multiple symptoms such as dyspnea and shortness of breath. The most common cause of heart failure are ischemic heart disease, which constitutes 50-75% of all heart failure. New York Heart Association Functional Classification is a classification function which is based on the patient's own experience of the disease and are graded from I to IV. A chronic disease can cause suffering of disease, suffering of life and suffering of care. Aim: To describe patients' experiences of how heart failure and its symptoms affect daily life. Method: A literature-based study, in which the result is based on eleven scientific articles. Results: Heart failure affects the whole person, both mentally and physically in daily life. Life becomes limited because of the somatic symptoms and emotional difficulties is also known. The feeling of isolation becomes evident when the patient cannot participate in activities. Quality of life deteriorates when the daily routines can no longer be performed. Conclusion: Heart failure has a clear impact in the patient's daily life in which the body is constantly changing. This leads to an unknown experience where the future is unpredictable. Heart failure is a condition where the whole person should be considered in order to alleviate suffering.
