【Abstract】 As the packing phase have an obvious nonlinear and time-varying feature,linear time-invariant models often fail to meet the modeling accuracy requirements.The conventional nonlinear modeling methods,such as the mechanism model,fuzzy and neural network model,do not fully utilize the repeatability to reduce modeling complexity.This paper presents an orthogonal-parameterized linear time-varying model for packing phase of injection molding process.The model can describe packing characteristics adequately while the method is simple and reliable.Experimental results verify the effectiveness of the algorithm.更多还原
