Kertas kerja ini mempersembahkan suatu pendekatan baru dalam mengawal sistem gantungan aktif. Pendekatan yang dicadangkan ialah menggunakan skim kawalan mod gelangsar perkadaran-pengkerbedaan. Menggunakan permukaan gelangsar jenis ini, kestabilan asimptotik sistem adalah lebih pasti berbanding dengan jenis permukaan gelangsar konvensional. Skim kawalan yang dicadangkan diaplikasikan penggunaannya dalam mereka bentuk sistem gantungan aktif automotif model kereta suku. Keupayaan sistem kawalan yang direka bentuk akan dibandingkan dengan sistem gantungan pasif yang sedia ada. Kajian dalam bentuk penyelakuan dijalankan untuk membuktikan keberkesanan reka bentuk sistem kawalan berkenaan. Kata kunci: Kawalan automotif; kawalan mod gelangsar; kawalan tegap; ketakpastian tak terpadan The purpose of this paper is to present a new approach in controlling an active suspension system. This approach utilized the proportional integral sliding mode control scheme. Using this type of sliding surface, the asymptotic stability of the system during sliding mode is assured compared to the conventional sliding surface. The proposed control scheme is applied in designing an automotive active suspension system for a quarter-car model and its performance is compared with the existing passive suspension system. A simulation study is performed to prove the effectiveness of this control design. Key words: Automotive control; sliding mode control; robust control; mismatched uncertaintiesDownloads
