A method determines at least one system state of a system using a Kalman filter. At least one measured value, measured by at least one sensor of the system, is supplied to the Kalman filter. The method includes estimating the at least one system state using the Kalman filter. An estimation result and at least one associated item of information relating to a reliability of the estimation result are output. The method further includes determining a discrepancy between at least one model value associated with the estimation result and at least one measured value associated with the estimation result, and correcting the at least one associated item of information relating to the reliability of the estimation result using the determined discrepancy.

Method for controlling an electric actuation assembly (1), the method comprising the following steps:

applying a plurality of known first output forces and recording a plurality of first input intensities for a first movement direction of the output;

establishing, by interpolation, a first characteristic function;

applying a plurality of second known output torques and recording (2) a plurality of second input currents for a second movement direction of the output opposite to the first direction;

establishing, by interpolation, a second characteristic function;

establishing, on the basis of the first characteristic function, the second characteristic function, a magnetic constant of the motor (11) and a reduction ratio of a gearbox (12), and a control correction coefficient;

controlling the actuation assembly (1) by applying the control correction coefficient.

Systems and methods of controlling the fan speed of one or more secondary variable speed cooling fans of an information handling system in real time by dynamically and adaptively shadowing the fan speed of another primary variable speed cooling fan or by so shadowing the fan speed of the variable cooling fan/s of a primary cooling fan zone including other variable speed primary cooling fans of the same information handling system.
