    摘要： Exemplary methods and systems for a distributed control system (DCS) in an industrial environment such as a plant. The DCS includes sensors for monitoring plant processes, and controllers for controlling plant processes. The sensors and controllers each have an associated communication protocol. The DCS also includes an interface that receives data from the sensors, translates the data into a common protocol, and generates control signals based on the translated data to the controllers over a network. The interface communicates with each sensor and controller based on their respective communication protocols.

    摘要： An apparatus and method for producing a hydrogen-enriched reformate. The apparatus includes a fuel processor for producing a reformate having fluctuations in a pressure and/or flow rate and means for reducing the fluctuations. The reformate comprises impurities that are removed by a purification unit having a plurality of adsorbent beds. A valve assembly controls the flow of reformate to the adsorbent beds based upon sensed product data generated by a product sensor. A compression unit optionally compresses the reformate prior to entering the purification unit. Means for reducing fluctuations in the pressure and/or flow rate include a buffer and/or a conduit for providing a controlled flow of a supplemental fluid to an inlet of the compression unit. A product valve can control the flow of hydrogen-enriched reformate out of the purification unit. A controller can control the valve assembly, the flow of supplemental fluid and the product valve among other apparatus components to maintain a stable pressure within the purification unit and to produce a desired hydrogen-enriched reformate.

    摘要： A method and apparatus are disclosed. The apparatus includes a store of at least one historical sensor measurement, a store of potential cut-off frequencies, and a filter. Each potential cut-off frequency is associated with a respective potential difference between a sensor measurement and the stored historical sensor measurement. The filter has a cut-off frequency dynamically selected from the stored potential cut-off frequencies on the basis of a difference between the stored historical sensor measurement and a current sensor measurement. The method includes determining a difference between a current sensor measurement and a historical sensor measurement; and dynamically selecting a cut-off frequency for a filter for the current sensor measurement from the difference.

    摘要： A control technique for use in a fuel processor is disclosed. In one aspect, a control system includes a subsystem manager controller the operation of a respective physical subsystem for each of a plurality of physical subsystems in the fuel processor. The subsystem managers take their direction from a master control manager. In a second aspect, the subsystem managers collectively form a layer operating in conjunction with a second layer capable of interfacing the subsystem managers to their respective physical subsystems, a third layer capable of interfacing the subsystem managers with the second layer. In a third aspect, master control manager manages the operation of each physical subsystem through a respective subsystem manager, directs state transitions of the subsystem managers, and routs interaction between the subsystem managers from the master control manager.
