METHOD AND SYSTEM FOR CONTROLLING THE PNEUMATIC PRESSURE IN A VOLUME

A method is described for controlling pneumatic pressure by actuating a charge and a discharge valve that vary the pressure, comprising, among other things, providing a matrix wherein each cell indicates a time for opening the charge or discharge valve; if the initial pressure value (PVi) in the volume is less than the target pressure value (PVt) to be reached, opening the charge valve, decreasing the value of the opening time indicated in the selected cell if the pressure value in the volume exceeds the target pressure value (PVt) and possibly increasing the value of the time indicated in the selected cell; if the initial pressure value (PVi) in the volume is greater than the target pressure value (PVt), opening the one discharge valve for the time indicated in a selected cell and possibly increasing the time value indicated in the selected cell and possibly decreasing the time value indicated in the selected cell.
