VOFB CONTROL OF NONLINEAR VIBRATION FOR ACTIVE SUSPENSION

Abstract

Abstract: A new robust adaptive control algorithm—VOFB (Variable-structure-control output feedback backstepping) control law applied to automobile active suspension is proposed. The stability is proved and simulated. A nonlinear filter is introduced which simplifies the control law design. An output-feedback state observer is designed. The analysis of VSC (Variable structure control) is introduced in Backstepping controller design. The robustness to system disturbance is gained.

Key words: Active suspension VOFB, Backstepping, Robustness, Continuous Timoshenko beam theory, Non-linear transient rotor-dynamics, Fan blade out
