In this study, a new approach for composing a delayed resonator structure with acceleration feedback is introduced. Classical delayed resonator is modified into an observer-based structure. Performance of the classical and observer-based delayed resonators are investigated on an experimental setup. Tuning parameters of delayed resonators are kept same for all process. Experimental results demonstrate the successful performance of the observer-based delayed resonator. (C) 2018, IFAC (International Federation of Automatic Control) Hosting by Elsevier Ltd.
