The Adaptive Kalman Filter Based on Improved Variable Oblivion Factor Least Square Arithmetic


Article Preview

Adopting improved variable oblivion factor least square arithmetic to real-time amend Kalman’s state transfer matrix, we put Maple Dam reservoir flood forecast real-time adjustment for example, then apply and compare with other ways. The result shows this arithmetic is preferable.
