Research on the Dynamic Characteristics of Lifting Hydraulic Cylinder of Jigger Based on Matlab/Simulink

To do the simulation of lifting hydraulic cylinder of moving sieve of jigger based on Matlab/Simulink,and by the research of response characteristics of lifting hydraulic cylinder to step signal,analyzes the dynamic characteristics of hydraulic cylinder as the variations in the pump displacement.Analysis results are the same as the application effect at a preparation plant of Xishan Coal and Electricity(Group) Co.,Ltd.
