摘要
将具有突变性质的害虫种群模型转化为标准尖角突变模型.运用化学防治手段,建立相应的具有脉冲效应的治理模型.利用优化脉冲控制原理,得到了最佳防治时刻及相应的种群水平,最后通过数值模拟验证结论的正确性.
The pest population model with catastrophe is changed into the corresponding standard form.By means of chemical controls,the corresponding control model with impulsive effect is proposed.According to the principle of optimization impulsive control,the controller is designed not only to get optimization control time but also to give the corresponding population level.Finally,the simulations are carried to prove the results.
