Abstract
The Rapid Estimation Scheme (RES) for estimation of states subject to unknown inputs has been described in Refs. 1 and 2. Kalman filter (KF) was observed to be divergent in some computer simulations when the states changed suddenly due to unknown inputs. This paper derives sufficient conditions for the convergence of KF after the occurrence of unknown inputs and also determines the conditions on the signal to noise ratio for the effectiveness of either KF or RES.
