Spatial fuzzy modeling for spatial parameter system
|
Abstract:
A new fuzzy modeling method is proposed for spatial parameter systems. First, On the basis of the 3-D fuzzy set, we propose an improved spatial fuzzy set consisting of a traditional fuzzy set and an additional dimension for spatial nformation. On the spatial axis, the traditional fuzzy membership function is extended along the spatial physical variation curve of the input variables, thus, the spatial variation of the input variable is described by the continuous variation of the membership function. Secondly, on the basis of the spatial fuzzy set, we make use of the spatial Mamdani fuzzy modeling format to develop a modeling method for building the fuzzy model of the spatial parameter system. The simulation verifies the effectiveness of this method.
