Electromagnetic Shunt Damping
A method for electromagnetic shunt damping (EMSD) will be presented in this paper. Compared to piezoelectric shunt damping, the proposed EMSD vibration controller has a number of bene ts. It requires small shunt voltages, can provide large stroke and can dampen larger mechanical structures. A passive control strategy is validated through experimentation on a simple electromagnetic mass-spring-d...
متن کاملNonlinear Damping of Injection Oscillations
General analytical procedure for determination of the transverse feedback system parameters with a nonlinear regime of injection oscillations damping in circular accelerators and colliders is described. For this feedback loop the dependence between the kick value in the deflector and the beam deviation at the pick-up location is a nonlinear function. The beam dynamic nonlinear equation of the t...
متن کاملA broadband controller for shunt piezoelectric damping of structural vibration
Abstract In this paper a broadband active shunt technique for controlling vibration in piezoelectric laminated structures is proposed. The effect of the negative capacitance controller is studied theoretically and then validated experimentally on a piezoelectric laminated simply supported plate. The ‘negative capacitance controller’ is similar in nature to passive shunt damping techniques, as a...
متن کاملNonlinear Damping in Micro ‐Speakers
The mechanical and acoustical losses considered in the lumped parameter modeling of electro-dynamical transducers may become a dominant source of nonlinear distortion in micro-speakers, tweeters, headphones and some horn compression drivers where the total quality factor Qts is not dominated by the electrical damping realized by a high force factor Bl and a low voice resistance Re. This paper p...
