An electronic valve controller for an open-loop and closed-loop control of a valve island includes four or eight valve disks having pneumatic valves configured to perform a motion task. Applications for the open-loop and closed-loop control of the valve island can be loaded onto the electronic valve controller. The invention further relates to a valve assembly, which is controlled in an open-loop and closed-loop manner by an electronic valve controller, to a corresponding method, and to a system.

Application-based control of pneumatic valve assemblies

An electronic execution unit controls and regulates a pneumatic valve assembly for a pneumatic movement. An application for controlling and regulating a valve assembly is or can be loaded so that it can be carried out on the electronic execution unit to carry out the pneumatic movement on the pneumatic valve assembly. An electronic valve controller for the open-loop control and closed-loop control of a valve assembly has at least one pneumatic valve for a pneumatic movement task.

Application-based control of a valve disk

A method for the supply of compressed air of a compressed-air consumer having two fluidically separate, kinematically coupled working areas, wherein each of the working areas is assigned to a valve arrangement which can be independently controlled and can be configured between a blocking position, a first functional position for a fluidically communicating connection to a fluid course and a second functional position for a fluidically communicating connection to a fluid sink and wherein each of the two valve arrangements is configured individually depending on a predefinable movement task for the compressed-air consumer and depending, on at least two pressure values from the following group: supply pressure, first working area pressure, second working area pressure, discharge pressure, for a provision of a predefinable developing for a fluid mass flow or for a provision of a predefinable developing for a fluid pressure in the respective working area or for a provision of a predefinable developing of a valve cross-section.

Method for the supply of compressed air to a compressed-air consumer, valve device and data carrier with a computer program

A method for operating a valve device for supplying compressed air to compressed air consumer includes the steps of: determination of a first fluid pressure in a first section of a fluid passage of a valve assembly, which extends between an inlet port, and a valve element, determination of a second fluid pressure in a second section of the fluid passage of the valve assembly, which extends between the valve element and an outlet port, determination of a flow value for the valve element from the two fluid pressures and of a flow function, relating of the flow value with a presettable volumetric fluid flow rate or mass fluid flow rate for the pressurised fluid, which flow rate is provided for flow through the fluid passage, to a guide value and determination of a required actuating energy for an actuating device, and provision of the actuating energy to the actuating device.

Method for operating a valve device, valve device and data storage medium with a computer program

A method for operating a multi-limb manipulator which includes electric actuators assigned to manipulator limbs, control units assigned to the actuators, including: the provision of desired movement values for the actuator to an actuator dynamic model and the determination of an electric desired current value for the actuator, the transfer of the desired current value to a controller designed for outputting an actuator current to the actuator with the inclusion of the desired current value and of a measured actual current value and a measured actual position of the actuator, wherein a difference between the desired current value and the actual current value is determined as a required positional deviation, and wherein the positional deviation is added to the desired distance fed into the actuator dynamic model to facilitate a diversion movement of the manipulator limb operated by the actuator on the occurrence of an external disturbing force.
