摘要
Driessen and Christiansen independently showed that for a specific dynamic model, the proportional-integral phase-locked loop (PLL) has the same structure as the Kalman filter. In this letter, closed-form expressions of the corresponding Kalman gain values are derived both in acquisition and tracking modes of the PLL.
