A Fast North-Finding Algorithm on the Moving Pedestal Based on the Technology of Extended State Observer (ESO) [PDF]
Sensors, 2022 We propose a kind of fast and high-precision alignment algorithm based on the ESO technology. Firstly, in order to solve the problems of rapid, high-accuracy, and anti-interference alignment on the moving pedestal in the north-seeker, the ESO technology in control theory is introduced to improve the traditional Kalman fine-alignment model.
