A high‐precision timing and frequency synchronization algorithm for multi‐h CPM signals

IET Communications, Volume 18, Issue 17, Page 1049-1061, October 2024.
This paper presents an innovative approach for achieving timing and frequency synchronization for multi‐h continuous phase modulation (CPM) signals. To rectify timing offset and mitigate the adverse effects of noise in received signals, a re‐configurable local filter generation method is integrated into the timing synchronization algorithm ...

Multi‐parameter identification method of induction motor based on coupling and small signal injection

IET Electric Power Applications, Volume 18, Issue 10, Page 1317-1331, October 2024.
The coupling relationship between the motor speed and the stator resistance is used, and an adaptive rate of them is designed based on the Lyapunov stability design law, which ensures the stability of parallel identification of speed, stator resistance, and rotor resistance.

Frequency-Locked Loops in Electrical Power and Energy Systems:Equivalent or Different to Phase-Locked Loops?

, 2021
In the electrical power and energy (EPE) area, the traditional concept in designing the synchronization system of power converters is using the phase-locked loop (PLL) concept. An alternative way is using the frequency-locked loop (FLL) concept, which is
