This document describes the work for the master’s thesis in Electrical Engineering carried out at Electrolux Laundry Systems. In this project the computers that control the laundry system have been compared in order to verify the performance of the whole system. Three real environment systems are analysed and two of these systems have been set up in the laboratory in order to solve the problem considered. The results show that the tested devices perform better than the device PC1, which is not fulfilling the expectations in the real environment system. Some conclusions and future work are presented.
