1-phase PLL:1相锁相环 输入:1相电压瞬时值。输出:瞬时频率、瞬时角度、瞬时角度的三角函数值(单粻厕救丿嚼搽楔敞盲sin、cos)该锁相环已经提供有角度值输出,你为什么还要用该角度的三角函数值再恢复角度值呢?
锁相环(Phase-locked Loop, PLL)的控制回路一般由鉴相器(Phase Detection,PD)、环路滤波器(Loop Filter, LF)以及压控振荡器(Voltage-controlled Oscillator, VCO)三部分组成。如下图所示。 输入信号v_i(t),输出信号v_o(t)。PLL的工作流程是:将输出v_{o}(t)反馈到输入端,经过环路的调节,实现v_{o}(t)...
可以做到。输入的是三相电压或电流,输出频率,A相的角度。设置好初始相位角和三相电的频率,以及PI参数。一般仿真中,初始相位角=0,频率50Hz,PI参数视情况调整(具体方法参加PID参数设置)。
求助大佬们,2016b版的matlab/simulink里Discrete 3-phase PLL在哪里呢?找不到,也搜索不到,是这一版没有这个模块吗? 羽幻凝 1L喂熊 1 up一下! c机帝的小号 打酱油的 5 这玩意得自己搭的吧 warmyang0416 1L喂熊 1 楼主解决这个问题了吗 我也遇到了这个问题 希望你可以教教我怎么弄 谢谢了 晚枫...

To overcome this issue, an adaptive-frequency PR controller is proposed in [12], in which a Phase-Locked Loop (PLL) is used to estimate the frequency of the 3-phase utility grid voltage. Nevertheless, when the 3-phase utility grid low-voltage is contaminated with harmonics and voltage ...
The design methodology is applied to three existing 3-phase PLL structures modelled in MATLAB/Simulink, and the proposed method is further evaluated through extensive simulations and performance comparisons with the traditional Wiener approach. To enhance the understanding of model behaviour and the ...

Synchronisation of the inverter and grid AC waveforms is achieved using a phase-locked-loop (PLL) circuit. An effective decoupling strategy based on fuzzy logic controllers (DFLC) is designed to eliminate the interaction between the two current components. The DC-link voltage is controlled using a...
