摘　　要：基于T-S模糊广义系统控制方法,研究了一类广义单种群生物经济模型的H∞控制问题.依据数学、生态和经济学理论建立一类用微分和代数方程联合描述的广义生物经济模型,并基于微分代数系统理论研究该类生物经济模型发生奇异诱导分岔(SIB)和脉冲行为.构造该系统的广义T-S模糊模型,设计T-S模糊广义系统的H∞控制器,消除系统中存在的奇异诱导分岔和脉冲行为,抑制种群变化,使系统趋于稳定,而且可以使控制能量保持在有界范围内.数值仿真说明了该控制器的有效性.H∞ control of a class of descriptor single-species bioeconomic models was studied with T-S fuzzy descriptor system control approache.According to the theory of mathematics,ecology and economics,a descriptor bioeconomic models was established with differential and algebraic equations.The singularity-induced bifurcation（SIB） and impulsive behavior of the bioeconomic model were researched with differential algebraic equations.T-S fuzzy descriptor model was constructed,and a H∞ controller for the T-S fuzzy descriptor system designed to eliminate the singularity-induced bifurcation and impulsive behavior,restrain the population change,make the model system stable and keep the cost energy within limited range.Numerical simulation illustrates the validity of the proposed controller.
