Abstract

The transitional response of filters such as the Bessel can be realized in closed loop servo systems without dependence on pole zero cancellation or step command shaping. This paper presents the theory by example of a straightforward design method for emulating a Bessel step response in a closed loop servo system. Design methods presented here are applicable for adapting most polynomial filter equations.
