摘　　要：给出以TMS320F2812处理器为核心的无传感器永磁同步电机(PMSM),控制系统方案的软、硬件设计过程。系统采用空间矢量脉宽调制技术和滑模变结构控制等智能控制策略,充分利用数字处理器(DSP)高速的运算能力和丰富的片上资源,实现系统的无传感器化和实时控制,使得系统具有良好的动态品质和稳态性能。This paper introduces a design of sensorless PMSM （Permanent Magnet Synchronous Motor） control system based on TMS320F2812. The performance characteristics and functions of TMS320 F2812 are presented. The composition of hardware and the design of software are discussed. This system adopts advanced control strategies, such as SVPWM, SMO, and uses high -speed count ability and abundant internal resource to realize non - sensor and real - time control. The system has good dynamic and stable properties and an extensively practical value.
