Design and implementation of an FPGA-based motor control IC for permanent magnet AC Servo motors

Abstract

This paper presents the design and implementation of a motor control IC for permanent magnet ac (PMAC) servo motors using the field programmable gate array (FPGA). This paper develops a hardware architecture for the digital control of PMAC servo motors. The proposed control structure has also been realized using FPGAs from Xilinx Inc. All the control functions, including the PWM waveform generation, current control, vector control, velocity control, and position control have been realized using FPGA based programmable logic gates. The constructed PMAC control IC includes 25,000 logic gates and is realized using 8-bit integer arithmetic, Experimental results are given to verify the PMAC control IC.
