摘　　要：基于风力发电变桨系统的需求,分析了永磁直流伺服电机的调速原理,提出了永磁直流电机控制策略,并研究建立了全数字直流伺服控制系统。选用TI公司的TMS320F2812DSP作为控制核心,介绍了该伺服驱动器的主功率电路和控制电路硬件设计、实现方法以及整体软件架构和具体实现流程。通过旋变解码试验和动态调速试验,验证了全数字直流伺服控制系统的整体设计。Based on the demand for pitch system of wind power,this paper analyzes the control principle of permanent magnet DC servo motor, proposes the control strategy of permanent magnet DC motor,and studies and has established a full digital DC servo control system. Using the TMS320F2812 DSP of TI Company as the control core,it introduces the hardware design of main power circuit and control circuit of the servo driver, the realization method,the overall software architecture and specific implementation process. Having done the resolver decoding speed test and dynamic test,verified the overall design of the full digital DC servo control system.
