Input shaping control of electronic cams

Abstract eng:
The paper deals with the input shaping control of electronic cams that eliminates their residual vibrations. The models of several different kinds of electronic cams are described, i.e. the simple traditional one, the serial one, the parallel one, the multi-input one. Then the input shaping control and its generalization is described. The generalization means the shaper of arbitrary time length and/or of arbitrary rate combined with the set of shaping functions of reentry kind. It is demonstrated and explained that some more complex shaping functions in comparison with the simple Heaviside pulse shapers are more robust against model misalignment. This generalized input shaping control is applied to different kinds of electronic cams.
