Radar Waveform Generator with Fuzzy Frequency Regulation [PDF]
: The Phase-Locked Loop (PLL) is a common functional component in many electrical systems. Phase-locked loops (PLLs) are closed-loop feedback-driven devices producing a signal depending on the frequency and phase of reference sig-nal that comes in.

Identification of Vibration Parameters in a Spacecraft using Kalman Filters, Numerical Search and Phase-Locked Loops [PDF]
Communication in space requires antennas that are accurately pointed. Often antennas are mounted on lightly damped space structures, that are easily set into vibration, which decreases the pointing accuracy of the antennas.
