Abstract :
The CARMA model of the systems are developed by system identification methods and its parameters are estimated. Moreover, the state space models of the systems are given according to the lemma of time sequence models and state space models. A new self-tuning filter is described. It comprises the recursive extended least square estimator, Kalman filter and noise statistical estimator. Applied to oil field systems, excellent results were obtained. Validity of the new scheme is indicated
