摘要
采用智能功率模块和TMS320F2812型DSP,完成了永磁同步电机(Permanent Magnet Synchronous Motor,简称PMSM)全数字交流伺服系统的设计与实现。介绍了系统的硬件设计,包括主电路、控制电路、基于IR2175的电流检测电路、复合式光电编码器的位置/速度检测电路以及保护电路的设计。分析了d,q轴中PMSM的数学模型和id=0的矢量控制策略,在CCS下采用模块化编程的思想实现了基于矢量控制的速度伺服系统。
The design and implementation of full-digital AC servo system based on permanent magnet synchronous motor（PMSM）is completed by use of the intelligent power module（IPM）and TMS320F2812 DSP.This article describes the hardware design of the system,including the main circuit,control circuit,current sampling circuit based on IR2175,the position/velocity sampling circuit based on hybrid optical encoder,the protection circuit design.The motor mathematical model in the d,q axis coordinate system and the id=0 vector control principle are analyzed.In the CCS,the speed servo sys-tem based on vector control is achieved under the modular programming ideology.
