Abstract

In this paper we present the state-of-the-art of field-oriented control of AC motors using fuzzy logic controllers. We describe our control system from both the software and hardware point of view. For implementing the control algorithm we have developed a DSP based single board controller. The board is based on Texas Instruments' TMS320C25 Digital Signal Processor. The board contains a configurable digital interface, which can be used to extend the functionality of the board by connecting analog and digital I/O peripherals. It has a flexible memory subsystem with EPROM, SRAM and nonvolatile SRAM support; an RS-232C serial port; a keypad with 6 keys; and four 7 segments LED display. The experimental results have been compared in the case of traditional PI type speed control, and show good dynamical behavior.
