This paper presents an enhanced predictive current control technique with fixed switching frequency applied to the 5-phase induction drives. This approach accurately predicts the required duty ratio for the PWM pulse for a given current reference in each digital time step using the vector space decomposition theory. The pulse width is calculated from an(More)
—This paper presents a self-sustaining mobile system for counting and classification of vehicles through processing video. It proposes a counting and classification algorithm divided in four steps that can be executed multiple times in parallel in a SBC (Single Board Computer), like the Raspberry Pi 2, in such a way that it can be implemented in real time.(More)
This paper presents the development of a protocol converter software (gateway) between two standards used by monitoring and control tasks in power electrical systems. At one side the legacy protocol IEC (International Electro-technical Commission) 60870-5-101 and on the other side the new protocol IEC 61850, which introduces a number of new concepts for the(More)
The development of SOA (service oriented architecture) applications is a paradigm to consider for the integration of services which usually requires the incorporation of distributed artificial intelligence technologies or multi agent systems (MAS) to achieve their objectives. This is the case of transportation field, where the improvement of urban data(More)
The wireless CORBA specification provides a basic framework for wireless based mobile distributed environments, suggesting a generic solution which still hides the underlying network level details from applications. However, its application over Bluetooth networks exhibits some problems when dealing with multi-user environments, like power consumption(More)
A basic framework for wireless based mobile distributed environments is given by the wireless CORBA specification. It provides a generic solution hiding the underlying network level details from applications. However, in Blue tooth networks, it exhibits some problems when dealing with multi-user environments, like power consumption limitations of mobile(More)
