Study on nonlinear forced vibration control system of a vertical wing plate

This study discussed the nonlinear forced vibration control (NFVC) design for a vertical wing plate system with piezoelectric actuators. The nonlinearity mainly considered the actuator’s input-output hysteresis nonlinearity in this paper. Also, the Prandtl-Ishlinskii (P-I) model is used to describe nonlinearity from the actuator. In addition, the nonlinear system’s stability is ensured by operator theory. And, the NFVC performance is guaranteed by designed operators and estimation structure, respectively. Finally, the simulation case study showed the effectiveness of the constructed system.
