| Abstract: | The control precision of two-cylinder synchronous system is seriously affected by strong nonlinear and coupling effects. The synchronous error aggravates the internal force of specimen deformation and has a strong failure ability. It is of great practical significance to study the synchronization control algorithm with excellent performance. The mathematical model of dual hydraulic cylinder synchronous control system is established, which considers installation error, measurement error and servo valve zero deviation. The influence mechanism of the above error factors on the accuracy of dual-cylinder synchronous control is analyzed. A dof control strategy based on internal force compensation and position compensation is proposed to achieve high precision position synchronization and output consistency of dual hydraulic cylinder. Finally, MATLAB/Simulink software was used to analyze the two-cylinder dof synchronization control algorithm and verify the effectiveness of the control strategy. |
