A measured position signal is fed to at least two channels which respectively contain a transformation component and an estimation filter. One channel (S1) covers transformation and estimation of the first derivative of the movement or the position parameter, and the second channel attends to the transformation and estimation of the other derivative of the movement or speed parameter. The output signal produced during the pivoting-inwards time at selected monitoring times is fed back to the inputs of the other channels, and the channel for the highest derivative takes care of estimation with a starting point that the highest derivative will accept the predetermined values, e.g. to be constant. A third channel transforms and estimates the third derivative of the movement or the acceleration parameter. The three channels incorporate inverse transformation components working with digital/analogue conversion. (Provisional basic advised week 86/33) |
