Semi-active dynamic vibration absorbers have one or both of the following capabilities: (a) initial displacements set to non-zero values and (b) damping adjustable in real time. Such devices are feasible because of the development of electro-rheological fluids and electromagnetic dampers. Experiment

โฆ Synopsis
A semi-active controller for excessive transient vibrations of resonant flexible structures is presented. The suggested controller technique is based upon using an impact damper with a variable clearance. Numerical simulations were employed to investigate the design parameters. Simple experiments were performed to demonstrate the feasibility of the damper.

When a flexible robot arm, a cantilevered beam type of structure, moves with a fast speed between workstations and is suddenly stopped after a new positioning is completed, excessive transient vibrations are produced as a result of the flexibility. An impact damping technique may be used to control
The development of an innovative approach for optimum vibration suppression of #exible structures is presented.

As a compromise between passive and active suspensions, a semi-active (SA) suspension scheme is suggested and demonstrated for both 1- and 4-degree-of-freedom (DOF) vehicle models. Because only limited number of vehicle aspects can be studied using a 1-DOF model, a more comprehensive 4-DOF model is
We investigate semi-active control for a wide class of systems with scalar nonlinear semi-active actuator dynamics and consider the problem of designing control laws that guarantee stability and provide sufficient performance. Requiring the semi-active actuator to satisfy two general conditions, we
