A compressor includes a control unit and a model unit. The control unit determines at least two actuation values of at least two actuating elements of the compressor via a transmitted setpoint value of a parameter of the compressor from a characteristic diagram of the compressor or at least two corrected actuation values of the at least two actuating elements via a model-based theoretical setpoint value from the characteristic diagram of the compressor. The model unit determines a model-based theoretical state of the compressor via the actuation values or the corrected actuation values by using a state model of the compressor. The model-based theoretical state of the compressor is described at least with the model-based theoretical setpoint value of the parameter of the compressor. The control unit controls at least one of the actuating elements as a function of the corrected actuation value of this actuating element.
