Electronic Signature Identification

Description: Modelling and simulation of electrical systems are fundamental tools to design reliable systems. However, in most cases high computational effort is required. In order to avoid this requirement, mathematical approaches are used to replace real circuit blocks. The use of these mathematical models known as black and grey boxes has increased over recent years. Consequently, the obtained results provide accuracy by using simpler models. Moreover, the information used to create these models is not limited by the confidentiality of manufacturers given the information is obtained by means of experiments only. This project focuses on the design of black and grey boxes for an induction machine fed by an inverter that can be used in the aircraft industry. Firstly, it presents an introduction of more electric aircraft concepts to justify the necessities of modelling the proposed system. Following this, some techniques were described to obtain black and grey boxes normally applied in previous publications. Chapter three describes the configuration of the system whilst specifying the assumptions and algorithms used. Chapter four presents the experiments that were carried out to obtain the models and the results are presented in the same section. Finally, a validation of the system is described in chapter five and some suggested models are presented. The conclusion and suggestion for future work are presented in chapter six.
