This paper is concerned with the stability analysis of positive polynomial-fuzzy-model-based control systems with time delay. Each of the polynomial fuzzy model and the polynomial fuzzy controller is allowed to have its own set of premise membership functions, which can improve the design and realization flexibility. Conditions showing the positivity of the system are first obtained. Then, to deal...
The complexity of LUCC (Land Use / Cover Change, LUCC) determines that it is important to conduct the study of LUCC using complex system theories, in particular by the establishment of a mathematical model for complex systems. In this paper, the LUCC model was built based on GIS technology, CA (cellular automata) and Agent technology. Firstly, Landsat TM data of 2000 and 2010 are used to obtain the...
In order to guide the city's waterlogging control, it's very necessary to research the urban waterlogging occurrence rules and how urbanization affects the urban waterlogging. In this paper, we select the catchment area located in Kunming Dongfeng East Road as study area to construct the urban waterlogging simulation model based on GIS and SWMM model. The procedure of model building contains sub-basin...
