通过锁相,可以获得输入网侧电压的频率,相位,频率等信息。 基于SOGI的PLL锁相技术存在以下几个优点: 实现简单 the generated orthogonal system is filtered without delay by the same structure due to its resonance at the fundamentalfrequency,所产生的正交系统由于是在基频处的共振可以被无延迟的滤波 产生的相差9...
a PLL consists of a phase/frequency detector (PFD), charge pump, loop filter, voltage controlled oscillator (VCO), and a clock divider in a feedback loop. The PFD and charge pump together produce an error signal proportional to
Use this setup to design different loop filters and verify your design. For example, use this PLL over a different operating frequency. Finally, to verify the PLL locking behavior in the time domain, probe and plot the output signal of the loop filter....

The step-response of the linearised PLL shows that there are oscillations and the settling time is about 0.1 s, this can also be seen in the nonlinear simulation in Figure 10. %Fri 27 May 2005 %pll filter design and linear analysis %run it before pll simulink run but make sure af and...
This example shows how to model a phase-locked loop (PLL) in the phase domain, compare the analytic results to simulation results in the time domain, and identify the advantages and disadvantages of each approach.
