A flow controller includes a valve unit for influencing the flow of a fluid through a fluid channel, a flow sensor for detecting the flow of the fluid through the fluid channel, a pressure sensor arrangement for detecting a fluid pressure of the fluid, and a control unit which is adapted to, in response to the flow being within a measurement range of the flow sensor, assume a first operating mode, and, in the first operating mode, to perform a first closed-loop flow control on the basis of the flow detected by the flow sensor, and, in response to the flow being outside the measurement range of the flow sensor, assume a second operating mode, and, in the second operating mode, to perform an open-loop flow control on the basis of the detected fluid pressure and/or to perform a second closed-loop flow control on the basis of the detected fluid pressure.

Flow controller, valve arrangement and method

A system, including: a fluidic actuator which can be acted upon by a pressurized fluid and has 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 act upon the fluidic actuator with the pressurized fluid in order to move the actuator member into a prescribed position, and a hose arrangement, including at least one hose via which the fluidic actuator is fluidically connected to the pressurized fluid provision device, wherein the pressurized fluid provision device is adapted to carry out the position control taking into account a system model describing the hose arrangement, the actuator and/or the pressurized fluid provision device.

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

A trajectory planning unit for providing a trajectory as a command variable for a control unit for position control of an actuator member of an actuator, wherein the trajectory planning unit is adapted to provide the trajectory on the basis of a target position curve and to limit the trajectory according to at least one limit value comprising a velocity limit value, an acceleration limit value, a braking acceleration limit value and/or a jerk limit value. The trajectory planning unit is adapted to provide the trajectory according to at least one specification value which can be specified, the specification value including an initial velocity value, a final velocity value, an initial acceleration value and/or a final acceleration value.

Trajectory planning unit, valve arrangement and method

A system (), including: a fluidic actuator () which can be acted upon by a pressurized fluid and has 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 fluid to the fluidic actuator () in order to move the actuator () into a prescribed position, the pressurized fluid provision device () being adapted to carry out the position control taking into account at least one system parameter, which describes a physical property of the system and/or a requirement parameter which defines a requirement for the positioning of the actuator (), wherein the pressurized fluid provision device () is further adapted to perform an assistance procedure and to determine and/or verify, within the assistance procedure, the system parameter and/or the requirement parameter on the basis of a movement of the actuator () and/or a consideration of physical limits.
