    摘要： A method and system are disclosed for controlling a process by establishing a control factor for a proportional-integral-derivative (PID) controller used to control a parameter of a process relative to a setpoint. A feedback signal regarding the parameter of the process is received via a sensor of the process and a first feedback loop. Automatic adjusting of the control factor of the PID controller is based on the feedback signal.

    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： 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 for operating a combustor having a catalyst bed. The method includes the steps of directing a flow of air through a catalyst bed, providing heat to the catalyst bed, sensing the temperature in an upstream portion of the catalyst bed to provide an upstream temperature, directing a flow of a fuel through the catalyst bed when the upstream temperature reaches a light-off temperature to produce a combustion reaction, increasing the flow of the fuel until the flow of air and the flow of fuel have a selected air to fuel ratio, and controlling the combustion reaction within the catalyst bed by adjusting the flow of air and the flow of fuel while maintaining the selected air to fuel ratio. The method can include sensing temperatures within the catalyst bed and controlling the combustion reaction in response to the sensed temperatures. The heat provided to the catalyst bed can also be adjusted in response to the sensed temperatures. The methods can further include exchanging heat between heated combustion products and one or more reforming reactants.
