| Abstract |
The application of Field Oriented Control represents a fundamental requirement in the development of AC drives. The best part of the applications, anyway, is dedicated to "small" motors with high speed commutating converters, able to reach extremely good
dynamic performances. The implementation on high power drives determines different kinds of problems arising from the difficulty of controlling the converter and the need of dealing with dynamic behaviours typical of large systems. In this paper the authors experience in the development of a high performance drive, composed by a salient pole synchronous motor, fed by a twelve-pulse no-circulating current cycloconverter, is described and the solutions used to solve the main control problems are presented. The implementation aspects on a microprocessor system based on VME-bus architecture and performance results on a 100 kV A prototype are also shown. |
