document: The analysis and control of longitudinal vibrations from wave viewpoint The analysis and control of longitudinal vibrations in a rod from feedback wave viewpoint are synthesized . Both collocated and noncollocated feedback wave control strategies are explored . The control design is based on the local properties of wave transmission and reflection in the vicinity of the control force applied area , hence there is no complex closed form solution involved . The controller is designed to achieve various goals , such as absorbing the incoming vibration energy , creating a vibration free zone and eliminating standing waves in the structure . The findings appear to be very useful in practice due to the simplicity in the implementation of the controllers
