摘要
针对麦蚜种群模型,在麦蚜种群出现快速增长时,引入冲失滤波器,使麦蚜种群快速下降并稳定在不危害小麦生长的状态,最后通过数值仿真验证该方法的正确性与有效性,为蚜虫种群的管理工作提供理论参考.
According to Logistic model,the aphid populations model with the washout filter is introduced based on the breakout of the aphid populations.The controller is designed to keep the aphid populations at refuge level.Finally the correctness of the method is verified by numerical simulations.The paper may provide the theoretical reference for aphid population management.
