20100233555 | CLOSED-LOOP CONTROL SYSTEM FOR A CONTROLLED SYSTEM - The invention relates to a closed-loop control system for a controlled system for specifying at least one controlling variable to the controlled system, having a primary controller, for generating the controlling variable within an interval between a maximum controlling variable barrier and a minimum controlling variable barrier. At least one measuring means for determining a controlled variable of the controlled system is provided. At least one measurement system for ascertaining at least one state variable of the controlled system, and at least one secondary controller, for varying the maximum controlling variable barrier and the minimum controlling variable barrier as a function of the state variable are provided. | 09-16-2010 |
20110223499 | FUEL CELL SYSTEM WITH ENERGY-EFFICIENT REACTANT RECYCLING - The invention relates to a fuel cell system with at least one fuel cell for electrochemical conversion of two reactants. The fuel cell has two electrode areas, having a first supply line for supplying a first reactant to a first electrode area, and an outlet line, for emission of residual gas from the first electrode area. The residual gas has an electrochemically unconsumed portion of the first reactant, a recirculation element, for feeding the residual gas from the outlet line into the first supply line, and an outlet valve in order to emit the residual gas into an area surrounding the fuel cell system. The invention provides for the fuel cell system to have a monitoring unit in order to control the outlet valve. In particular, the monitoring unit opens the outlet valve when the energy required to feed the residual gas by the recirculation element exceeds an energy potential of the first reactant which is present in the residual gas. | 09-15-2011 |
20130101913 | METHOD FOR OPERATING A FUEL CELL AND FUEL CELL SYSTEM WITH IMPROVED THERMAL CONTROL - The present invention relates to a method for operating a fuel cell system, comprising the following method steps: | 04-25-2013 |

20140174079 | METHOD FOR REGULATING A BOOST PRESSURE OF AN ENGINE - In a method for regulating a boost pressure of an engine which has a compressor, an actual boost pressure and a setpoint boost pressure are used as input parameters. The setpoint boost pressure is regulated in such a way that a pressure ratio in the compressor does not exceed a limit pressure ratio. A reference boost pressure is ascertained based on a speed of the engine and a load of the engine. A flow and/or a pressure of air supplied to the engine is/are detected and an associated flow signal and/or pressure signal is generated. The smaller of the reference boost pressure and a limit boost pressure is used as a setpoint boost pressure. The limit boost pressure is ascertained based on a limit boost pressure ratio and a speed of the compressor. | 06-26-2014 |
