Semi-active Fuzzy Sliding Mode Control for Floating Raft Isolation System

Abstract

Abstract: A semi-active static output feedback fuzzy sliding mode controller is designed for floating raft isolation system with electro-rheological (ER) damper. Sliding surface matrix is selected in accordance with Hurwitz stable judgement of sliding mode motion equation. Force transmissibility, input force and output force response of floating raft isolation system, respectively, under chirp exciting signal and dual-frequency exciting signal are simulated. The simulation results indicate that the performance of floating raft isolation system designed with semi-active static output feedback fuzzy sliding mode control method is remarkably better than those of optimally passive damping.

Key words: Floating raft, Fuzzy sliding mode, Semi-active, Vibration isolation system
