A UNIVERSAL CONTROL SYS FOR FIELD-ORIENTED CONTROL OF AC MACHINES - TMS320C14

The purpose of this paper is to present a universal controller system used in field oriented control method of ac machines. This controller system uses one Texas Instruments (TI(TM)) TMS320C14 digital signal processor (DSP), four analog-to-digital converters (ADC), three operation amplifiers, two current sensors and a resolver. The digital values of sine and cosine functions of the rotor position are found without using the resolver-to-digital converter (RDC). This method is tested in the field-oriented control of a synchronous machine. The experimental results proved the validity of this controller system.
