摘要:

利用Floquet乘子理论、 小振幅扰动技巧和比较定理研究一类定期脉冲释放病毒颗粒和自然天敌的害虫综合治理模型在脉冲控制策略下系统解的稳定性, 给出了在脉冲控制下这类系统解的全局渐近稳定性及系统持续生存的充分条件. 数值仿真验证了推理结果.

关键词: 脉冲, 全局渐近稳定, 一致持久

Abstract:

The stability of a pest management viral infection system with impulsive releases of viral particles and natural enemies was researched by means of Floquet’s theorem, smallamplitude perturbation skills and comparison theorem. The sufficient conditions of globally asymptotic stability of pesteradication periodic solution and the permanence of the system controlled by that controller were obtained. Finally the mathematical findings were illustrated by numerical simulations.

Key words: impulsive, global stability, uniform permanence
