摘　　要：文章设计完成了一套基于旋转变压器检测无刷直流电机转子位置并实现换向功能的数字伺服舵机系统,采用TMS320F2812作为系统的控制核心,在介绍正余弦型旋转变压器的基本工作原理的同时,设计了旋转变压器与DSP和驱动器的接口电路及相关外围电路,并利用专用旋变解码模块实现电机换向位置信息的解算。经试验证明,该改进舵机控制电路能够实现伺服系统的功能,克服原霍尔换向系统缺点。This paper designs a rotary transformer based on detecting rotor position of Brushless DC motor and reversing function of digital servo actuator system, using TMS320F2812 as the core of the control system, the basic working principle of the cosine type rotary transformer at the same time, the design of the interface circuit of rotary transformer and DSP and drives and related peripheral circuit, and using the special resolver decoding module to realize the motor commutation position information solution. The experimental results show that the improved steering gear control circuit can realize the function of servo system and overcome the shortcomings of the original Holzer commutation system.
