The Research of Electro-hydraulic Proportional Control on Copper Anode Lifting Platform
This paper introduces the structure and working principle of the designed copper anode lifting platform.According to the actual working conditions and the structure of the lifting device,hydraulic system of electro-hydraulic proportional synchronous lifting device is designed and its working principle is analyzed.This paper takes the electro-hydraulic synchronization system as a research subject,whose mathematic model is established.To solve the synchronization accuracy of the hydraulic cylinder movement in the lifting process,a model reference adaptive controller is designed which is based on hyperstability theory.Both system simulation models of traditional PID control and adaptive control are established respectively in the software of Matlab/Simulink.Through the simulation result we can learn that adaptive control is batter than the PID control.Two hydrauliccylinders synchronization error is less than 0.02mm.
