Biological control is the artificial manipulation of natural enemies of a pest for its regulation to densities below a threshold for economic damage. The authors address the biological control of a class of pest population models using a model-based robust feedback approach. The proposed control framework is based on a recursive cascade control scheme exploiting the chained form of pest population models and the use of virtual inputs. The robust feedback is formulated considering the non-linear model uncertainties via a simple and intuitive control design. Numerical results on three pest biological control problems show that the proposed model-based robust feedback can regulate the pest population at the desired reference via the manipulation of a biological control action despite model uncertainties.

使用基于模型的稳健反馈进行生物害虫防治。

生物防治是对害虫天敌的人工操作，将其密度控制在经济损失阈值以下。作者使用基于模型的稳健反馈方法解决了一类害虫种群模型的生物控制问题。所提出的控制框架基于递归级联控制方案，利用链式害虫种群模型和虚拟输入的使用。通过简单直观的控制设计，考虑非线性模型的不确定性，制定了稳健的反馈。三个害虫生物控制问题的数值结果表明，尽管模型存在不确定性，但所提出的基于模型的鲁棒反馈可以通过操纵生物控制行为将害虫种群调节到所需的参考值。
