摘　　要：生态位在生态系统中发挥着重要作用,用新的修正的正态模糊集下的格贴近度作为零阶的Ⅰ型T—S模糊控制的后件来研究生态位,在生物学上有很强的实际意义.讨论如此给出的模糊推理系统同样是一个万能逼近器,用梯度下降法优化后件参数,并根据Lyapunov稳定性定理分析该系统是稳定的.最后通过实例仿真说明该方法是切实有效的.Niche plays an important role in the eco-system.It is of great practical significance in the field of biology to make researches on niche by using a modified normal fuzzy sets lattice close degree as the after piece of zero-order typeⅠ T-S fuzzy control.The fuzzy inference system is a universal approximator,and the gradient descent method is used to optimize the after-piece parameters.The system is proved to be stable by Lyapunov Stability Theory.Besides,simulation is made to demonstrate that the method is feasible and effective.
