Abstract
A system and method for controlling the acceleration of an armature of an electric drive by generating a high quality acceleration error correction signal z, the system comprising an accelerometer for obtaining a measured armature acceleration value bm, which is equal to the product of a true armature acceleration &agr;, and an acceleration measurement transfer function Fg(p), and means for obtaining a measured acceleration signal, bEm, which is generated from a measured substitute acceleration signal bE·bm and bEm are scaled such that the relationship of bm=&agr;·Fg(p)=bEm·Fg(p) is satisfied. The measured armature acceleration signal bm is filtered with a first filter transfer function of FT(p), and the measured acceleration signal bEm is filtered with a second filter transfer function of FH(p). The first and second filter outputs are combined to form the partly synthesized high quality acceleration error correction signal z=bm·FT(p)+bEm·FH(p).
