System and method including a fluidic actuator and a pressurized fluid provision device

A system comprising:

• a pneumatic actuator, which can be acted upon by pressurized air, the pneumatic actuator having an actuator member;
• a pressurized fluid provision device which is adapted to carry out a position control of the actuator member and, within the position control, to apply the pressurized air to the pneumatic actuator in order to move the actuator member into a prescribed position;
• and
• a hose arrangement comprising at least one hose via which the pneumatic actuator is fluidically connected to the pressurized fluid provision device,
• wherein the pressurized fluid provision device is adapted to perform the position control taking into account a system model comprising a hose model describing the hose arrangement, and
• wherein the pressurized fluid provision device has a pressure sensor arrangement which is adapted to measure a pressure of the pressurized air at the pressurized fluid provision device and to provide the measured pressure as a measurement pressure, and wherein the pressurized fluid provision device is adapted to calculate a pressure of the pressurized air at the pneumatic actuator using the hose model and the measurement pressure and to provide the calculated pressure as a calculation pressure.

A system comprising:

• a fluidic actuator, which can be acted upon by a pressurized fluid, the fluidic actuator having an actuator member;
