Investigation of the mechanical and electrical properties of actuators for active vibration isolation , Southampton, GB University of Southampton 50pp.
(ISVR Technical Memorandum, 989).
In this report, the mechanical and electrical properties of three types of actuators are investigated. The actuators of interest are electromagnetic, magnetostrictive and piezoelectric. The constitutive equation of each actuator is presented in the form of a two-port model. The models are validated by comparing numerical simulation results with experimental data. A demonstration of controller design for active vibration isolation system using an electromagnetic actuator and a magnetostrictive actuator are also presented. The effects of using a current driver or a voltage driver with the actuator are discussed.
