基于ARM的空调用PMSM矢量控制系统优化研究

Study-optimized on PMSM Vector Control Based on ARM in Air Conditioner

在对矢量控制技术原理研究的基础上,结合对一种电压空间矢量控制快速算法和一种新型的转子定位方法的初步研究,以ATMEL公司的AT91SAM7A3(ARM7TDMI内核)为主控芯片,提出一种空调用无位置传感器永磁同步电机控制系统优化设计方案,为新一代智能变频空调的控制系统设计提供新的思路和参考。

Based on the microchip of ATMEL's AT91SAM7A3 with the intelligent property of ARM7TDMI,vector control technology about sensorless permanent magnet synchronous motor(PMSM) in air conditioner is studied in this paper.Using an algorithm optimized of space vector pulse width modulation(SVPWM)and a novel method of State-Estimation,a variable frequency vector control system is designed for sensorless PMSM in air conditioner in order to provide a reference for the application study of new air conditioner control system.
