摘要

收起

单相锁相环PLL（phase-locked loop）被广泛应用于电力系统等相关领域，目前传统的单相锁相环算法存在计算量大、计算方法复杂等问题，并且在输入信号频率变化明显的场合使用效果会受到影响。针对这些问题提出了一种基于正弦跟踪非线性控制的单相PLL，采用基于李雅普诺夫稳定性的设计方法，实现了输入信号频率变化时PLL的全局收敛。在PSIM软件中搭建该新型PLL的仿真模型，并将所提方法与基于二阶广义积分器的传统单相PLL的应用效果进行比较，利用TMS320F28069数字信号处理器进行实验验证。仿真和实验表明，该算法能改善传统二阶广义积分器在频率突变场合下输出精度变差的问题，且算法简单、响应迅速。

Abstract

收起

Single-phase phase-locked loop (PLL) is widely used in fields such as power systems. However, the traditional single-phase PLL algorithms face challenges such as high computational complexity and complicated calculation methods. Moreover, their performance is affected in scenarios where the frequency of the input signal undergoes significant changes. A single-phase phase-locked loop based on sinusoidal tracking nonlinear control is proposed to address these issues. Using a Lyapunov stability-based design method, global convergence is achieved when the input signal frequency changes. A simulation model of this new PLL is constructed in PSIM and the application effects of the proposed method are compared with the conventional single-phase PLL based on the second-order generalized integrator, an experimental test is completed using the TMS320F28069 digital signal processor. Simulations and experiments indicate that the algorithm, with its simplicity and fast response, can improve the accuracy degradation issue occurring in traditional second-order generalized integrators during abrupt frequency changes.

Key words

Single-phase phase-locked loop / nonlinear control / Lyapunov’s stability theorem / second-order generalized integrator
