基于STM32F103的双轴交流伺服系统

针对传统单轴交流伺服系统存在体积大和成本高的问题，为满足工业自动化行业对结构紧凑型伺服驱动的需要，设计了一种全数字双轴永磁同步电机伺服系统。在分析了伺服系统实现原理和软硬件方案的基础上，该系统充分利用了STM32F103的2个高级定时器、3个高速AD、2个正交编码器接口等丰富的片上资源，采用了单个STM32F103为主控制器，以两块智能功率模块（IPM）为功率电路，使系统结构紧凑。实验结果表明，该双轴驱动器的性能能够满足实际使用的需求。

Dual axis AC servo system based on STM32F103

Aiming at the problems of large volume and high cost on traditional single-axis servo drive, to meet the needs of servo drive with a compact structure in the industrial automation market, a dual-axis digital permanent magnet synchronous motor（PMSM） servo system was designed based on a single STM32F103. Two advanced control timers, three high speed AD, two quadrature encoders and other on chip resources were used. Two IPMs were constructed as the parallel inverter. Synchronous control algorithm was also designed in the program. The system is compact, and the experimental results show that the performance of this dual axis servo drive can meet the requiements in the application.
