N2 - In order to fully describe the dynamic behavior of the magnetic levitation ball system which has nonlinear, open-loop instable and rapid response characteristics, RBF-ARX model with linear functional weights (LFWRBF-ARX model) was established.

This model varies with the working-point, it is a locally linear ARX model when the working-point is fixed and it becomes a globally nonlinear ARX model when the working-point changes. According to the model structure, a structured nonlinear parameter optimization method (SNPOM) was applied to identify the structure, linear and nonlinear parameters of model. Then the identified model-based predictive controller was designed. The results show that the LFWRBF-ARX model may capture the local and global dynamic characteristics of the magnetic levitation ball system well, and the ball may be controlled to levitate stably.
