摘要
针对三容水箱液位系统的非线性,采用RBF-ARX模型对三容液位系统进行了离线动态特性建模的研究。着重讨论了RBF-ARX模型结构的选取、模型参数辨识、RBF参数优化等问题。RBF-ARX模型与ARX模型的一步预测输出比较的结果证实了RBF-ARX模型在非线性系统建模中的优越性。
Three-tank water level system was modeled by using RBF-ARX model. The design of the structure of RBF- ARX model, model parameter identification, and radical basis function （RBF） parameters optimization were discussed particularly. Compared with the ARX model in 1-step predictive control, the results show the superiority of the RBF-ARX model in the modeling of nonlinear systems.
