Implementation of Vector Control system for 3ΦInduction Motor |
| Abstract |
In recent year, inverters and cycloconverters system are widely used for fed induction motor drives. Motor drives by cycloconverter is possible to frequency have been directly changed without AC/DC converter, so that circuits is simpler than inverter. A aims of this paper is the control strategy and hardware design for vector control system by cycloconverter fed induction motor drives. In this paper, Algorithm of vector control is derived from the model of controlled current source-fed induction motor. Vector control system is implemented using these algorithm and a pulse width controled cycloconverter using a SCR. Cycloconverter of vector control system is controlled by pulse width of SCR"s trigger signal. pulse width is controlled primary command current ㅣi₁ㅣ and frequency ω₁. Vector control system is used to investigate experimentally the performance of an in duction motor drive system. The system has the facility for continuous control of both the frequency and magnitude of the output voltage to keep a constant flux in the induction motors. |
