Pressure-Based Soft Sensors for Fast Volume Estimation

Abstract:

To acquire a fast method for better volume estimation, a novel soft sensor technique is proposed in this paper. Based on the principle of energy conservation as well as the ideal gas law, mathematical models of charging and discharging process are set up. Afterwards, simulations are carried out to explore the relationship between the estimated volume and the pressure stable time. Finally, experiments with different pneumatic cylinders are conducted to select the suitable estimation mode and also optimize the parameters. Results show that in discharging mode, the average estimation error for volume estimation can be less than 4% with both low pressure and high pressure, making this method quite suitable for industrial application.
