A feed-through truncated plate model which minimizing the effect of truncated modes on spatial low-frequency dynamics of the system by adding a spatial zero frequency term to the truncated model is provided and numerical software MATLAB is used to compare the feed-through truncated plate model with traditional balanced reduction plate model which is used to decrease the dimensions and orders of the infinite-dimensional and very high-order plate model. Active vibration control strategy is presented for a flexible plate structure with bonded three self-sensing magnetic transducers which guarantee unconditional stability of the closed-loop system similar as collocated control system. Both multi-mode SISO and MIMO control laws based upon positive position feedback is developed for plate structure vibration suppression. The proposed multi-mode PPF controllers can be tuned to a chosen number of modes and increase the damping of the plate structure so as to minimize the chosen number of resonant responses. Stability conditions for multi-mode SISO and MIMO PPF controllers are derived to allow for a feed-through term in the model of the plate structure which is needed to ensure little perturbation in the in-bandwidth zeros of the model. A minimization criterion based on the H∞ norm of the closed-loop system is solved by a genetic algorithm to derive optimal parameters of the controllers. Numerical simulation and experimental implementation are performed to verify the effectiveness of multi-mode SISO and MIMO PPF contr\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Zhonghui Wu\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3668270716\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783668270718\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Grin Verlag\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 01\/03\/2017\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 178\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.53lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.27h x 5.83w x 0.41d","brand":"Zhonghui Wu","offers":[{"title":"Paperback","offer_id":48437339095295,"sku":"9783668270718","price":95.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_bc7adafa-fc39-4482-86dc-559f58d16005.jpg?v=1777161147","url":"https:\/\/www.whiterainbookhouse.com\/products\/multi-mode-active-vibration-control-using-zhonghui-wu-9783668270718","provider":"WR Book House","version":"1.0","type":"link"}
