Target speed prediction for a compressor or compressing device of a compressed-air supply system

A compressed-air supply system comprising:

• at least one compressed-air consumer;
• a plurality of compressed-air lines;
• a plurality of electrically controllable valves;
• a compressed-air controller for actuating the electrically controllable valves;
• a compressor having an electric motor as a drive;
• said compressed-air controller having a request signal input for a request signal, which represents a request made to the compressed-air supply system, and a consumer pressure signal input for a compressed-air consumer pressure signal, which represents a value of a pressure in said at least one compressed-air consumer;
• said compressed-air controller being configured, in response to the request signal, to:
• evaluate a current pressure consumer pressure signal with respect to a target state of said at least one compressed-air consumer corresponding to the request signal;
• to determine, depending on the target state of said at least one compressed-air consumer defined by the request signal and also on the actual state of the compressed-air supply system characterized by the current pressure consumer pressure signal, operating specifications for at least one of a target speed of the electric motor and an open operating mode or closed operating mode of the compressed-air supply system such that a specified maximum motor current is not exceeded until the target state of said at least one compressed-air consumer is reached;
• and,
• to output control signals corresponding to the operating specifications for at least one of the target speed of said electric motor and the open operating mode or the closed operating mode of the compressed-air supply system.
