  • METHOD FOR REGULATING AN ACTUAL VALUE OF A VARIABLE CHARACTERIZING A POSITION OF AN ACTUATOR, COMPUTER PROGRAM PRODUCT, COMPUTER PROGRAM, AND RECORDING MEDIUM
    Publication number: 20100191789
    Abstract: A method is provided for regulating an actual value of a variable, which characterizes a position of an actuator, to a setpoint value using a regulator, which method makes it possible to optimize regulation in terms of bandwidth, stability, accuracy, and sturdiness. A predefined time characteristic of the setpoint value is transformed into a desired time characteristic of the actual value. A first transfer function is formed in the frequency domain and is approximated using one or more factors, in particular delay elements, to transform the predefined time characteristic of the setpoint value into the desired time characteristic of the actual value. A nonintegral exponent is selected for at least one of the factors.

  • Method for operating an internal combustion engine
    Patent number: 7377240
    Abstract: In a method for controlling an actuating device of a valve element of an intake system and/or an exhaust gas system of the internal combustion using an actuating variable, a periodic compensation signal is applied, at least intermittently, to the actuating device. The compensation signal generates a periodic counterforce at the valve element which is directed in the opposite direction from the periodic force exerted by the undesired disturbing vibrations of the valve element.
