A Finite-time Estimation For Updating Look-up Tables

In this paper the problem of look-up table parameters updating is studied to cope with physical systems changes due to operating conditions and age. To this aim, an estimation algorithm is developed in order to update look-up table parameters in a finite-time. The convergence proofs are presented by Lyapunov-based approach, and the results are given based on the regressor model related to the identifiability condition. The estimation error is analyzed for the proposed algorithm. The validity of the presented algorithm is verified through the discharge coefficient map of the gasoline engine form enDYNA.
