Energy Regenerative and Active Control of Electro-Dynamic Vibration Damper
Active vibration control is introduced to an electro-dynamic regenerative vibration damper. It is intended to improve vibration reduction capability using the regenerated energy. This idea is applied to a moving mass type vibration absorber and vibration control is performed. In the case of energy regenerative control, a PWM step-up chopper is used to solve the dead zone problem. Active control signal is also produced by the other PWM chopper from the power supply. However, energy regenerative and active control mode can not operate at the same time. A new control law is introduced to switch control mode and to follow the ideal force. The ideal force is calculated using the LQ control theory. Experimental setup is made to confirm the proposed technique and the damping capability is tested.
