【Abstract】 A modeling method for nonlinear stochastics dynamic system(NSDS) based on neural network and extended Kalman filter(EKF) is presented. Using this method, the contaminated data by noise can be filtered by EKF. A dynamic neural network(DNN) which is a good approximation to the deterministic part of the NSDS can be obtained. Meanwhile the DNN can be used as a state estimator for the NSDS. In the end of the paper a simulation is shown.更多还原
