... 1 ,2]. Traditionally, rotor field-oriented control (RFOC) has methods, the torque and stator flux vector can be regulated permitted fast transient response by decoupling torque and with PI controllers, and the required voltage vector can be flux control [3]. This control strategy exploits the fact that in applied to ...

... the vicinity of the loop antenna. The most important problem is the shifting of the resonance frequency. Because of this frequency shift, there is no optimal energy coupling between the RFID tag and the loop antenna, resulting in a weak performance and low reliability. Tuning the antenna in a static metal environment could be a ...

... possibly implemented on different platforms and using multiple programming languages). Some of the key principles of service- orientation that are specific to SOA paradigm are: loose coupling, autonomy, reusability, composability, abstraction from underlying logic and discoverability [8]. SOA is a concept for large heterogeneous distributed systems, in which ...
