Description

technical field [0001] The invention relates to the technical field of electric cylinder control, in particular to a high-precision and rapid loading control method for electric cylinder pressure. Background technique [0002] With the continuous improvement of automation level and the continuous pursuit of efficiency and precision, pressure loading devices are more and more used in parts processing, assembly, testing and use. For occasions where the pressure is low and the control accuracy is not high, the pneumatic system is more economical at present; for applications that only require high pressure, the hydraulic system is the most widely used. For the increasingly emerging precision testing industry, the pressure loading requires fast speed, high pressure and high control precision, and the cylinder drive cannot meet the requirements; although the hydraulic cylinder drive can achieve high-precision and high-pressure loading with the assistance of a complex control syste...

Problems solved by technology

For the increasingly emerging precision testing industry, the pressure loading requires fast speed, high pressure and high control precision, and the cylinder drive cannot meet the requirements; although the hydraulic cylinder drive can achieve high-precision and high-pressure loading with the assistance of a complex control system, but There are defects such as slow loading speed, high maintenance cost, and unfriendly environment; as an emerging electric actuator, electric cylinders have the advantages of maintenance-free, large load, fast response, and environmental friendliness. In terms of position control and speed control of moving parts It is widely used, but there is no better control method for the application of electric cylinder to achieve high precision pressure and high response loading
