【Abstract】 According to the multimodels combining idea, a new online modeling method based on the preset models combination for Volterra series model is presented to reduce the computation for online modeling of Volterra series model of nonlinear systems. The current Volterra series model of the detected system is online obtained by (combining) some preset models. The formula and method of the model combining are established. Simulation results indicate that the presented method has better modeling precision, and efficiently reduces the computation burden of online modeling for Volterra models, and is easily realized in engineering application.更多还原
