Аннотация:The snag of common linear filtered Inverse Control (AIC) method is modify to hold with the characteristic of non-linear object with time delay and corresponding filtered ∈-adaptive Algorithm based on Real-Time Recurrent Learning (RTRL) is presented to identify the parameters and d controller.The simulation result on a non model of "The R.O.V. Zeefakkel" and Adaptive PID control keeps the same dynamic response performance, and also mathematical model for ship Course keeping be discussed.A neural network adaptive filter is introduced for the removal of impulse noise in digital images.
