Abstract
Method for the determination for an actual speed of a movable displacement element wherein an acceleration sensor is used to record an acceleration (a), and a position sensor is used to record a measured position of a displacement element. A model speed (vM) and a measured speed (v1) are determined by integration and differentiation, respectively. The model speed (vM) is used to determine an actual speed (v). The model speed (vM) and the measured speed (v1) are subtracted from one another. The difference is supplied to a controller (13) having an integral component, whose output signal is added to the acceleration (a).

A method for the determination of an actual speed of a movable displacement element, comprising:
- recording an acceleration of the displacement element with an acceleration sensor;
- determining a model speed of the displacement element by integrating the acceleration recording;
- recording a measured position of the displacement element using a position sensor;
- determining a measured speed of the displacement element by differentiating the measured position;
- determining the actual speed of the displacement element on the basis of the model speed by subtracting the model speed and the measured speed from one another, and supplying the difference to a controller having an integral component, the output signal of which is added to the acceleration recording.
