| 摘 要： | 提出了一种基于电控伺服变量柱塞泵的植保机变量施药控制方法,推导并建立了包含参数不确定性和扰动的施药流量模型,设计了鲁棒H∞最优控制器并证明其鲁棒稳定性,并转化为线性矩阵不等式求解控制器参数。本研究弥补了传统优化控制方法对于不确定性反应较为敏感的不足,与传统的线性二次型最优控制相比具有一定的快速性和鲁棒性优势,能够满足复杂作业条件下植保机精准变量施药要求,有效提高了农药利用率。

| Abstract: | A variable control method for plant protection boom spray based on electronically controlled servo variable displacement piston pump is proposed.The application flow model including parameter uncertainty and disturbance was deduced and established.The robust optimal controller was designed and proved.Rod stability is transformed into a linear matrix inequality to solve controller parameters.It makes up for the shortcomings of the traditional optimization control method which is sensitive to the uncertainty response.Compared with the traditional linear quadratic optimal control,it has certain rapidity and robustness,and can meet the plant protection machine variables under complex working conditions.The requirements for pesticide application have effectively improved the utilization rate of pesticides. |
