An Equivalent Transformation Based Method to Optimize T-S-K Fuzzy Control Systems and Its Functions in Controller Design
【摘要】 针对T S K模糊控制系统分区线性化综合方法,本文提出了基于模糊规则分解与合并的等价优化方法,并且从理论上论证了这种优化方法的两种作用,从而可以有效地优化不确定项的上界估计值,改善分区线性化综合方法的应用效果.*
【Abstract】 A method based on rule equivalent decomposing and merging to optimize the piecewise linear synthesis method for T S K fuzzy control systems is presented in this paper. Two major functions are proved theoretically. Therefore, the estimated upper bound of the uncertain terms can be optimized effectively. In turn, the application effect of the piecewise linear synthesis method for T S K fuzzy control systems is improved.
