A field orientation scheme for current-fed induction motor drives that is based on the closed-loop control of the torque angle is presented. Merits of the scheme are insensitivity to the rotor resistance and simplicity of implementation. The limits of the conventional field orientation solutions are reviewed. The scheme is then formulated, and its(More)
The paper gives an overview of the communication architectures adopted in the industrial automation for the electrical drives, ensuring a fast data exchange and high performance control. An attempt is made at defining real-time operation for this application field, at reviewing the standardization work done to unify the electrical drive interfaces, and at(More)
The Power Line technology has received an increasing attention in the last decades due to its inherent benefits, mainly related to the reduction of cabling and associated costs. Power Line Communication (PLC) was first employed in power utilities, and since the 80s in home automation, too. However, its use in the automotive field received relatively little(More)
The authors discuss electric drives currently employed in robotics and evaluate their performance in comparison with new kinds of motors now available. The importance of the control system in view of the motion coordination of different drives is stressed. In order to reliably evaluate these aspects, the authors propose an articulated structure to be(More)
A novel code for the analysis of extended x-ray absorption fine structure (EXAFS) data collected in total reflection mode (reflEXAFS) is presented. The procedure calculates the theoretical fine structure signals appearing in the reflectivity spectrum starting from the ab initio EXAFS calculations. These signals are then used in complex structural refinement(More)
