摘要

摘要: 生态位在生态系统中起着重要作用，type-2直接T-S模糊控制在稳定一类具有参数不确定性的非线性系统时，具有很好的可操作性.将系统的生物个体的进化特性、自适应性与直接T-S模糊type-2控制方法相结合,以生态位贴近度函数作为type-2 T-S模糊控制的后件,构造具有生物特性的type-2直接T-S模糊控制方法,求得生态位生态因子的自适应律,反映了生物个体的自适应利用环境的程度,运用Lyapunov方法分析系统稳定性，并通过实例仿真对比分析得出type-2在稳定性和收敛性上是优于type-1的.此方法的提出有利于环境的和谐和生态系统的稳定及生态环境的可持续发展,也使模糊控制有了实际的物理背景.

Abstract: Given the important role of niches in the ecosystem and the operability of type-2 direct T-S fuzzy control of the stability of a class of nonlinear systems with parameter uncertainties, the biological individuals’ evolutionary characteristics and adaptive behaviors were integrated with the direct T-S fuzzy type-2 control method, and the niche closeness function was used as a follow-up to type-2 T-S fuzzy control parts. Besides, a type-2 direct T-S fuzzy control method with biological characteristics was proposed to find the niche ecology. The self-adaptation rate of the factor reflects the degree of the adaptive use of the environment by biological individuals. Through comparison of simulation examples, this study reveals that type-2 is superior to type-1 in terms of stability and convergence. The study shows that the type-2 method is conducive to environmental harmony, ecological stability and sustainable development of ecological environment; in the meantime, this method gives fuzzy control a practical physical background.
