Publication number: 20220243718Abstract: A method is for producing, for a hydraulic machine having an actuator, a setpoint-value trajectory satisfying predefined limitations in order to influence an output variable of the hydraulic machine. A trajectory of unlimited setpoint values is fed to a trajectory planning function, which produces the setpoint-value trajectory from the trajectory of unlimited setpoint values. In the trajectory planning function, the trajectory of unlimited setpoint values is differentiated at least twice in order to obtain a trajectory of unlimited setpoint values that is differentiated n times. In the trajectory planning function, at least one limitation is applied to the differentiated trajectory of unlimited setpoint values in order to obtain a differentiated trajectory of limited setpoint values. The differentiated trajectory of limited setpoint values is fed to a filter integrator chain in order to obtain the setpoint-value trajectory.Type: ApplicationFiled: July 2, 2020Publication date: August 4, 2022Inventors: Steffen Mutschler, Adrian Trachte, Carolina Passenberg, Steffen Joos

Patent number: 10683148Abstract: A tank filling device for a liquid container has a base body with mounting end to secure the base body on a liquid container. An actuating section is disposed in the base body interior and slidable lengthwise relative to the base body. A liquid valve is connected to an outlet opening for liquid and controls the outlet opening by being coupled to the actuating section such that the liquid valve is manually opened or closed by moving the actuating section. An air channel with air inlet and air outlet supplies air into the liquid container for pressure compensation. The air channel extends from the liquid valve toward the mounting end and has an air valve at the air outlet.
