| Abstract: | A nonlinear stochastic system model is composed according to linear filter and spectral decomposition theorem and shaping filter principle.Combing an approach that linear dynamic tangent plane is used to approximate a general nonlinear system on operating point.Based on the generalized criterion function and optimal prediction algorithm,the unknown parameters are identified by using NARMAX model parameter estimation of nonlinear recursive algorithm.An adapative prediction algorithm is also proposed.The simulation studies show the effectiveness of the algorithm. |
