Abstract:
A method for controlling an internal combustion engine, comprising the steps of:allocating a control deviation and a governor to each cylinder of the internal combustion engine, each governor preselecting a cylinder-specific triggering signal on the basis of the allocated control deviation; ascertaining cylinder-specific actual values on the basis of a signal from a sensor arranged in an exhaust train; performing a comparison of the ascertained cylinder-specific values to a setpoint value; specifying triggering signals for a cylinder-individual control of at least one of a fuel quantity and an air quantity on the basis of the comparison; causing at least two filtering elements to filter the signal of the sensor arranged in the exhaust train; and determining at least two frequency-specific actual values, a setpoint value, and frequency-specific control deviations on the basis of the filtered signal.
