Abstract: 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.

Abstract: 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.

Abstract: A method for determining stability of a vehicle having a load suspended from the vehicle is provided. The method can include obtaining measurements from a plurality of sensors positioned on the vehicle, obtaining a measurement from a vehicle accelerometer operative to determine an inclination of the vehicle, determining a position of the load suspended from the vehicle, determining a slung load of the load suspended from the vehicle, using the determined slung load and the determined position of the load suspended from the vehicle, determining tipping moments acting on the vehicle, determining righting moments acting on the vehicle and determining a tipping stability based on the determined tipping moments and determined righting moments.

Abstract: A pipelayer machine is provided. The pipelayer machine has a main body, a boom pivotally connected to a first side of the main body, a hook winch provided on the first side of the main body and a boom winch provided on the second side of the main body. The boom winch and the hook winch can be connected to a structural assembly that positions the boom winch proximate the second side of the main body and positions the hook winch proximate the first side of the main body of the pipelayer machine. The hook winch can be provided in a hook winch frame and the hook winch frame can form a structural member in the structural assembly.
