Synchronous Control of Multi-Integrated System of Electro-Hydraulic with Mechanic Based on Virtual Axis Model
The article gives a solution to the precise synchronous control of multi-hydraulic cylinders which exist in the large-sized pressure and flattening machine by the virtual axis method. To fulfill the job, the scheme introduces the acceleration feedback to the virtual control model to make the model practical. According to the Newton’s mechanical law and fluid mechanic, the article set up the model mentioned above. The control system presented is investigated through simulation of Matlab under step disturbance and productive practice which successfully demonstrate the effectiveness of the proposed control model.
