Mechanical Systems Design C16 Vibration Reduction pdf

... dynamics of flexible mechanical systems that require vibration reduction are usually mathemati- cally represented by partial differential equations (PDEs). Specifically, flexible systems are modeled by ... crane systems, and flexible cable systems. More recently, Zhang et al. 16 and Nagarkatti et al. 17 designed boundary controllers for nonlinear string models and axially ac...
