|Title:||Boundary-controlled travelling and standing waves in cascaded lumped systems||Authors:||O'Connor, William

In most cases the control system for each actuator requires identifying and measuring notional component waves, propagating in opposite directions, through the actuator-system interfaces. These measured component waves are then used to form the control inputs to the actuators. The paper also shows how the boundaries can be actively controlled to establish and maintain standing waves of arbitrary standing wave ratio, including those corresponding to classical modes of vibration with textbook boundary conditions. The proposed control systems are also robust to system disturbances: they react quickly to overcome external transient disturbances to re-establish the desired steady motion.||Type of material:||Conference Publication||Publisher:||Elsevier||Copyright (published version):||2012 ElsevierLtd||Keywords:||Travelling waves; Standing waves; Boundary control; Lumped systems; Mass–spring systems; Standing wave ratio||DOI:||10.1016/j.ymssp.2012.02.005||Language:||en||Status of Item:||Peer reviewed||Conference Details:||The 2nd Joint International Conference on Multibody System Dynamics , Stuttgart, Germany, May, 2012|
