There is a treasure trove of articles and white papers about designing with Kalman filters and PLLs on Embedded.com, as well as on their use in some surprising venues. I have linked to some of these ...

This project implements a real-time fluid simulation engine on embedded hardware. The liquid reacts to board tilt using the MPU6050 IMU with a Kalman filter for pitch and roll estimation. The ...

Abstract: This paper presents an experimental comparison between a digital phase-locked loop (PLL) and an extended Kalman filter (EKF) implemented as frequency estimators on identical embedded ...

As a follow-on course to "Kalman Filter Boot Camp", this course derives the steps of the linear Kalman filter to give understanding regarding how to adjust the method to applications that violate the ...
