Abstract : The problem of the on-line state estimation for a nonlinear process subjected to some unknown inputs is studied for both standard extended filtering and the rapid estimation scheme. The rapid estimation is derived from a specific cost functional and is used for estimating the initial values of the states and the states immediately following the application of the unknown input. The digital computer evaluation of the rapid estimation scheme for tracking a thrust maneuvering space vehicle shows that the estimates of the states by the rapid estimation scheme is superior to the results obtained from the standard extended filtering technique.
