在传统同步参考坐标系锁相环( SRF-PLL)解码算法的基础上介绍了一种双同步参考坐标系锁相环( DSRF-PLL)解码算法。由于旋转变压器在实际应用中受本体设计及信号处理电路的影响，其输出往往为包含误差的非理想信号，其中幅值不平衡和相位非正交误差占主要地位。 DSRF-PLL算法将非理想信号分解成一个正序电压分量和一个负序电压分量，通过双同步坐标系( DSRF)和解耦网络结构单元来达到消除幅值不平衡和相位非正交两种误差的目的。在MATLAB/Simulink环境下搭建仿真模型对DSRF-PLL解码算法进行了仿真验证。仿真结果表明该算法在抑制旋转变压器输出幅值平衡和相位非正交误差方面的有效性。

A double synchronous reference frame-based phase-locked loop ( DSRF-PLL) decoding algorithm was studied in this thesis based on the traditional synchronous reference frame-based phase-locked loop ( SRF-PLL ) decoding method. In practical application the output signals of the resolvers were always non-ideal for the influence of the design of the motor structure and the peripheral circuits, among them amplitude error and non-orthogonal error dominate. In DSRF-PLL the non-ideal signals were decomposed by a positive sequence voltage and a negative sequence voltage; The amplitude error and the non-orthogonal error were eliminated by the double synchronous reference frame ( DSRF ) and the decoupling network unit. The DSRF-PLL decoding algorithm was verified by simulation in the MATLAB/Simulink, and the simulation results showed that the algorithm could achieve expected effect to deal with the amplitude and the orthogonal errors.
