摘要
为了提高磨砂机在溶剂和水基油墨分散研磨中的控制性能,提出基于变结构滑模控制的磨砂机在溶剂和水基油墨分散研磨中的优化控制方法,构建溶剂和水基油墨分散研磨中磨砂机优化控制约束参量模型,以磨砂机比例压力阀流入容器的溶剂和水基油墨的流量为基准量进行多模控制,建立水基油墨输出压力与控制信号的比例关系模型,采用三阶非线性系统进行溶剂和水基油墨分散研磨中的磨砂机控制,结合模糊神经网络和变结构滑模控制方法实现控制律的改进设计。仿真结果表明,采用该方法进行磨砂机在溶剂和水基油墨分散研磨控制的稳定性较好,溶剂和水基油墨分散研磨的自适应控制能力较强。
In order to improve the control performance of sanding machine in solvent and water-based ink dispersion grinding,the optimal control method of abrasive machine in solvent and water-based ink dispersion grinding based on variable structure sliding mode control is proposed.The optimal control constraint parameter model of solvent and water-based ink dispersion grinding machine is constructed,and the multi-mode control is carried out based on the solvent and water-based ink flow rate of the proportional pressure valve of the grinder.The proportional relationship model between output pressure and control signal of water-based ink is established.The third-order nonlinear system is used to control the sanding machine in solvent and water-based ink dispersion grinding,and the fuzzy neural network and variable structure sliding mode control method are combined to realize the improved design of the control law.The simulation results show that this method has good stability in solvent and water-based ink dispersion grinding control,and the adaptive control ability of solvent and water-based ink dispersion grinding is strong.
