Abstract

A 2-mass rotary system is widely used in industrial applications. Torsional resonance, however, usually appears in such the system. This article presents an attempt to suppress torsional resonance and to improve the performance of a system. With two-degree-of-freedom (2-DOF) configuration, feedforward and feedback compensators are used. The former provides desired performance of the system, while the latter suppresses resonance. The design approach is transfer function synthesis based on pole-zero assignment. Moreover, to gain better performance of the overall system, the adaptive tabu search (ATS) method, one of the AI search techniques, is applied. The satisfactory response has been achieved without torsional resonance.
