| 摘 要： | 单相锁相环技术对于一些需要电压相位信息的控制场合具有重要意义。本文提出一种单相锁相环新算法,算法基于同步坐标旋转变换,通过反馈解耦的方法简化了锁相环的结构,同时避免了滤波器带宽受到系统动态性能要求制约的问题。文中在介绍基于同步旋转变换的单相锁相环方法基础上,给出了改进算法的推导过程,并对新算法中的调节器参数进行了设计。仿真与实验结果验证了该新算法的有效性。

| Abstract: | Single-phase locked loop(SPLL) technology plays an important role in process controlling which phase information is needed.In this paper,a novel SPLL algorithm is presented.The algorithm is based on synchronous reference frame and its structure is simplified by means of feedback decouple method.The algorithm widens the bandwidth of the filter so as to get a good dynamic performance.In this paper,the principle of the conventional SPLL method which is based on synchronous reference frame is introduced and then the alternative method is deduced.Furthermore,the controller is designed.The results of the simulations and experiments both testify the efficiency of the presented algorithm. |
