Methods, systems, and devices of a control system for gas flow. The control system controls gas flow through a fuel cell stack of a vehicle. The control system includes two or more components including one or more actuators and a fuel cell. The control system includes an electronic control unit connected to the two or more components. The control system is configured to determine initial values and previous timestep values. The control system is configured to determine or estimate a total pressure of the gas flow in each of the two or more components based on the initial values and the previous timestep values. The control system is configured to control the one or more actuators based on the total pressure of the gas flow in each of the two or more components. 用于气体流的控制系统的方法、系统和设备，该控制系统控制通过交通工具的燃料电池组的气体流。该控制系统包括两个或更多个部件，所述部件包括燃料电池和一个或多个执行器。该控制系统包括连接至所述两个或更多个部件的电子控制单元。该控制系统构造成确定初始值和先前时间步长值。控制系统构造成基于初始值和先前时间步长值来确定或估算所述两个或更多个部件中的每个部件中的气体流的总压力。该控制系统构造成基于所述两个或更多个部件中的每个部件中的气体流的总压力来控制所述一个或多个执行器。
