英文摘要

      A structure for inverse identification of dynamic linear or non-linear system using neural network is presented. Two types of closed-loop control schemes that combine the neural network inverse model with PID are proposed. The dynamic feed forward multilayer network for identification and control is trained by a novel learning algorithm based on U-D factorization Kalman filter (UDK). The potentials of the proposed structure and schemes are demonstrated by simulation studies.
