The invention relates to a method for controlling a thermodynamic cycle process apparatus, in particular an ORC apparatus, wherein the thermodynamic cycle process apparatus comprises an evaporator, anexpansion machine, a condenser and a feed pump, and the expansion machine is coupled to an external apparatus in normal operation, and wherein the method comprises the following steps: measuring an exhaust steam pressure downstream of the expansion machine; and setting a volume flow of the feed pump in accordance with a computer-implemented control model of the thermodynamic cycle process apparatus according to the measured exhaust steam pressure and a target rotational speed of the expansion machine as input variables of the control model and with the volume flow of the feed pump as an output variable of the control model. The invention further relates to a corresponding thermodynamic cycle process apparatus. 本发明涉及一种用于调节热力学循环设备、特别是ORC设备的方法，其中热力学循环设备包括蒸发器、膨胀机、冷凝器和供给泵，并且膨胀机在正常运行中与外部设备联接，并且该方法包括以下步骤：测量膨胀机下游的乏汽压力；并且
