| Abstract: | To solve the problem of high maintenance cost of electro-hydraulic servo valve in common strip running deviation control system, an electro-hydraulic control system with proportion valve is designed. Mathematical model of the system is estabhshed and simulated. While stability of the system is analyzed, sine wave response of the system is obtained with MATLAB/SIMULINK. At the same time, the accuracy and the speed of response of the system are analyzed. The result indicates that the system can satisfy the request both of stability and accuracy of the strip running deviation control system. |
