摘要
基于对控制系统的建模方法,提出了面向液压系统数学模型的“灰箱”建模法。在对压滤机的液压控制系统重新设计的基础上,利用“灰箱”建模理论建立了液压系统的数学模型,运用Matlab中的Simulink软件包对该系统进行了动态特性数字仿真。实测和运行验证了改造后的液压系统工作可靠性与稳定性得到提高,为改善压滤机液压控制系统性能奠定了良好的基础。
Based on modelling for control system, a “grey--box” modelling strategy of the mathematics modelling for hydraulic system is proposed. And based on the rebuilt hydraulic system, by using the “grey--box” modelling theory, the mathematical modelling of hydraulic system was set up. The hydraulic system was simulated by Simulink software package of Matlab, and the results from simulation testify that the reliability and stability can be improved by on-the-spot survey and running the rebuilt hydraulic system. All of these designs, measures and researches make it available for improving hydraulic system in filter press in the future.
