Abstract:
A m odified skyhook-based sem -i active contro ller is proposed for imp lem enting an asymm etric con tro l suspens ion design w ith symm e tric MR dam pers. The contro ller has po tentia l to e ffective ly m in im ize the sw itching and hysteretic e ffects from the sem -i active contro l and theMR-dam per. The proposed contro ller is constructed w ith the qua rter-v eh ic leMR- suspens ion m ode,l and its re lative response characteristics are thus eva luated in term s of defined performancem easures under vary ing am plitude harm on ic, rounded pulse and random ex citations. The sens itiv ity o f the sem -i active suspension perform ance to variations in controller pa rame ters is further evaluated. The results illustrate that the proposed skyhook-based asymm e tric sem -i activeMR-suspension has super io r robustness on the contro ller param ete r var ia tions, and can ach ieve des irablem ult-i body suspension performances
