Structural control plays an important role in suppressing structural vibration under different loads. During a severe earthquake, a structure will exhibit nonlinear behaviors. In this case, the control method for structural nonlinear vibration is important for further study. In this paper, a semiactive control method considering the nonlinear magnetorheological (MR) damper model is proposed for structural vibration control. Due to the complexity of the structural and damper models, fuzzy systems are used to approximate these models. Based on these fuzzy systems, a sliding mode control method is developed, and the chattering phenomenon is mitigated by a fuzzy controller. Numerical simulations are conducted on the third-generation nonlinear benchmark model with the proposed structural control. The results verify the effectiveness of the proposed method.
