    摘要: A method for controlling a combustion process, in particular in a firing chamber of a fossil-fired steam generator, is provided. The method includes determining spatially resolved measuring values in the firing chamber. Spatially resolved measuring values are transformed into state variables that may be used for control engineering, and they are subsequently fed as actual values to control circuits. The changes in the controlled variables determined in the control circuits are divided among a plurality of actuators in a backward transformation considering an optimization target. A corresponding combustion system is also provided.

    摘要: A method for filtering a signal is proposed. A noisy input signal is continuously examined in order to determine whether the input signal it is within or outside a deadband. The deadband width and the zero point of the deadband are continuously adapted to the noise power of the input signal depending on the time behavior of the input signal and a predefined system time constant. At least one filtered output signal is continuously output, such as a deadband signal, which substantially corresponds to a smoothed input signal.

    摘要: A method for identifying a delay-susceptible control path in the control of a steam generator and a device constructed for carrying out the method are provided. A model structure of the steam generator is specified, consisting of an unknown time-variable Nth-order delay element and a known integrator. Also used for the identification are measurements of the fuel mass flow, the turbine stream mass flow, and the live stream pressure which arises in the steam accumulator behind the steam generator after the removal of the turbine steam mass flow. Using these online measurements and the model structure, the live steam mass flow at the output of the steam generator is derived by calculation. In this way, the input value and the output value of the Nth-order delay element are determined and, using an estimation method, the parameters of a continuous transmission function of the Nth-order delay element are also determined online.
