本文提出了一类新的基于生态位模型的Type-2模糊控制系统，将含参数的生态位贴近度函数作为模糊规则的后件，从而构成了Type-2 Takagi-Sugeno(T-S)模糊控制模型。主要采用Lyapunov方法设计控制器，利用梯度下降法优化参数，得到参数的自适应律。建立的模糊T-S模型具有生物个体的自适应性，可以确保整个系统的稳定性，通过prey-predator生态模型验证了该类控制器的有效性。%A new Type-2 fuzzy control system based on niche of ecosystem is proposed. Regarding the approach degree function of niche with unknown parameters as the consequent of fuzzy rules ,the T-S fuzzy control model on niche is constructed. The controller is designed by using the method of the Lyapunov and the consequent parameters are determined by using a gradient descent method. Finally the adaptive low of consequent parameters is obtained. The fuzzy system is based on niche embodied biological individual's adaptability,which can make the closed-loop system stable. Simulation of two-dimensional prey-predator system model is carried out to verify the effectiveness.
