摘要： T-S模糊系统被广泛应用在基于数据的建模方法中.模糊规则作为T-S模糊系统的核心,是影响系统精度和泛化性能的重要因素,然而模糊规则数量的确定非常困难.考虑基于减聚类的规则生成方法中,聚类半径直接影响规则生成数量,采用均匀设计设定聚类半径,合理选择规则数量,简化了复杂多变量系统的建模问题.实例证明所提出基于均匀设计思想的聚类半径设定法简单易行,具有较好的实际应用价值,适合于复杂多变量系统的建模应用.

Abstract: T-S fuzzy system is widely applied to different data-based modeling methods. As the core of T-S system, the fuzzy rule sets is the most important factor to the precision and generalization of the system, but the number of fuzzy rules is very difficult to determine. Taking account of how these rules are generated in view of cluster subtraction, the cluster radius (CR) affects the number of rules directly. Thus, the uniform design is chosen to set the cluster radius so as to determine the number of rules easier and simplify the modeling of complex multi-variable system. The effectiveness of the method proposed is verified through a simulation example.
