Abstract
Nonlinearity plays a crucial role in engineering systems and cannot be overlooked in structural design, dynamic response analysis, and parameter selection. This presentation will provide an up-to-date overview of a novel approach to robust control of nonlinear vibration systems by leveraging potential nonlinear benefits. Key points include:
1.Introducing beneficial nonlinearity in stiffness or damping as a dynamic reference model for nonlinear vibration control systems can enhance control performance and robustness while significantly reducing energy costs compared to traditional methods.
2.Inherent nonlinearity can be effectively utilized rather than eliminated, as is common in traditional methods.
3.Various practical issues related to robustness and adaptability of a control system can be addressed using this beneficial nonlinear reference model-based control scheme.
Extensive experimental results validate the claimed performance and suggest a promising, energy-saving, and innovative robust control approach.
