Pre‐filter design for tracking error specifications in QFT
Edward Boje · International Journal of Robust and Nonlinear Control · 2003
Abstract This note shows how the pre‐filter may be designed in quantitative feedback design of single‐input, single‐output systems with tracking error specifications (Eitelberg, Automatica, 2000; 36(2):319). The method uses gain and phase information for the pre‐filter design. The design is conveniently performed on the log polar complex plane using standard CAD tools.
