摘　　要：针对一类云杉蚜虫与其天敌的相互作用模型,引入一种具有生物特性的模糊自适应控制器。根据参数的自适应律,调整控制系统参数,使天敌-害虫的种群密度渐进地跟踪理想轨迹,保证了该系统的稳定性;计算机仿真说明了控制效果,为生态系统的持续平衡发展提供了理论依据。Aiming at some spruce aphides and their predator interaction model, a kind of self-adaptive fuzzy controller with the biological characteristics was introduced. According to the parameter adaptive law, the parameters in control system were adjusted to make the population density of sparuce aphides and their predator track the ideal trajectory and erasure the stability of the system. Computer simulation demonstrated the control effect, which provided the theoretical basis for the sustainable and balanced development of the ecological system.

关 键 词：生态位 贴近度函数 自适应模糊控制
