Delay-based input command shapers: frequency properties and finite-dimensional alternatives
Original language description
ZV, ZVD, EI, and other related delay-based input command shapers have been in the center of attention for decades and have given rise to many papers focusing on new more robust and/or optimal additions to the classical Smiths 1950s PosiCast idea. All considerations are nevertheless based almost purely on the time-domain reasoning, accompanied by some simple zero-pole plots. However, these shapers are in fact ordinary LTI systems (linear, time invariant), though infinite-dimensional (w/o finite state space representation, due to presence of delays), and feature interesting frequency notch-filter-like behaviour. The paper is devoted to presentation and discussion of the shapers' frequency responses, and to suggestions for finite dimensional (read: low order rational-transfer-function) alternatives, with implications towards practical implementation and feedback interconnections with input shapers. Performance of such filters is then assesed by means of a case study.
