Techniques are described for implementing automated control systems to control operations of target physical systems and/or their components (e.g., a fuel cell, wind turbine, HVAC unit, etc.), such as based at least in part on models of their dynamic non-linear behaviors that are generated by gathering and analyzing information about their operations under varying conditions. The techniques may include, for each of multiple levels of inputs to the system/component and/or other factors, injecting a corresponding signal input into the system/component, and using active sensors to collect time changes of the responses to these pulses. Information about the inputs and the responses is used to generate an incremental parametric model representing the internal state and behavioral dynamics of the system/component, which is further used to control additional ongoing operations of the system/component (e.g., to control whether and how much output is produced in a current or future time period).

An apparatus for providing operation logic of a fuel cell system may include an activation part configured to perform activation on a fuel cell, and an operating performance part configured to perform constant current operation according to the performing of activation.

According to an embodiment, a method of monitoring the operation of a device includes determining a plurality of operational parameters that are indicative of an operation condition of the device. A difference between each operational parameter and a corresponding limit on that parameter is determined. Each limit indicates a value of the corresponding operational parameter that corresponds to an undesirable operation condition of the device. An action index is determined based on at least a smallest one of the determined differences. A determination is made whether the action index is within a range corresponding to desirable operation of the device.

A method for controlling a power assembly comprising a fuel cell unit and an electric energy storage system for storing excess electric energy produced by the fuel cell unit. The method comprises predicting a power demand from the power assembly over a prediction time horizon, obtaining a state-of-charge and/or power capability of the electric energy storage system, based on the predicted power demand and the obtained SoC and/or power capability, identifying a time period during which the power assembly is expected to be able to deliver power in accordance with the predicted power demand with the fuel cell unit shut down, or is at least expected to be able to deliver power at a minimum power level determined with respect to the predicted power demand, controlling the power assembly to shut down the fuel cell unit during at least a part of the identified time period in response to the identified time period being larger than a time threshold.
