Abstract :
The performance of existing dead time compensation controllers for both non-integrating and integrating plants with large time delays is improved by an online estimation scheme. The estimation scheme uses a backpropagation-type update law for estimating simultaneously the plant time delay and static gain. Fuzzy logic is used to tune the estimator performance. Simulation results are provided to illustrate the scheme´s performance.
