Integral‐type half‐tangent phase‐locked loop for more electric aircraft grids

چکیده
In this paper, an integral-type half-tangent phase-locked loop (IHTan-PLL) is proposed for the varying-frequency AC grids of more electric aircraft (MEA). First, performance synchronous reference frame (SRF-PLL) and (HTan-PLL) discussed from a large-signal viewpoint. When frequency changes largely, SRF-PLL has many oscillations endures rather long transient process. The HTan-PLL can address large jumps. However, with harmonic disturbances, still in estimating when jumps largely. To enhance HTan-PLL, IHTan-PLL developed disturbances. performs better than addressing Specifically, under any changes, converges to equilibrium point (0,0), no emerge. addition, steady-state accuracy HTan-PLL. experimental results also demonstrate superior IHTan-PLL.
