The Control of Mechanical Impedance Using an Electrodynamic Actuator

Comeaga Constantin Daniel, Mitiu Mihaela, and Dontu Grigore Octavian
Abstract—The paper presents a study regarding the practical use of electrodynamic actuators for controlling the mechanical impedance and mobility of a 1 degree-of-fredom system, with application to transmissibility control. The electrodynamic actuators included in the structure of mechanical systems could be used as a semi-active solution to control the global mechanical parameters but with limitations due to the intrinsic electric properties of the actuator. An improvement of this technique is the the active solution based on different control laws and different variables (speed, acceleration, current), able to provide equivalent electrical parameters difficult to obtain by construction or even to introduce new properties in the system. The current study presents the principles used for this type of control and also shows some limitations due to the lack of stability for some ranges and types of feedback.

Index Terms—Active vibration control, semi-active vibration control, electrodynamic actuator.
