Abstract:

Valveless servo system is a new technology which is widely used in recent years. Compared to the traditional hydraulic system, valveless servo system has a lot of advantages such as high efficiency, less pollution and saving energy, which will be the main research direction of the hydraulic control in the future. Roll bending machine is a large industrial machine, but the efficiency of existing hydraulic system of roll bending machine is low and the cost of maintenance management is high. Applying valveless system on roll bending machine can overcome these defects. This paper made a study of the control strategies which were about valveless servo system on roll bending machine. And software MATLAB was used to do simulation experiment on valveless servo system. This paper summarized the steady-state error and dynamic characteristics according to output signals in different input signals.
