Sensorless Speed Control of Induction Motor Based on System-On-A-Chip Design

원칩 설계에 의한 유도전동기의 센서리스 속도제어

Recently effective system-on-a-chip design methodology is developed, and ASIC chip design is much studied for motor control. This paper investigates the design and implementation of ASIC chip for sensorless speed control of induction motor using VHDL which is a standarded hardware description language. The sensorless control strategy is to design an adaptive state observer for flux estimation and to estimate the rotor speed from the estimated rotor flux and stator current. The presented system is implemented using a simple electronic circuit based on FPGA.
