Semi-active vibration control based on unsymmetrical synchronized switching damping: Circuit design:
Journal of Intelligent Material Systems and Structures, 2015Co-Authors: Jinhao Qiu, Zhang Jin, Hong Nie, Li ChengAbstract:An unsymmetrical switch circuit is designed for semi-active control method based on synchronized switching damping principle of piezoelectric actuators. A Bypass Capacitor and an additional switch are used to realize unsymmetrical bipolar voltage. The control logic of the switches is introduced in detail and the switched voltages, which directly influence the control performance, are derived as functions of the vibration amplitude and the outputs of the voltage sources. Experiments were carried out to verify the designed circuit and the theoretical results of the switched voltage. For simplification of experimental conditions, the beam is fully clamped and the voltage is fully generated by the voltage source. The influence of the voltage source and Bypass Capacitor on the actuator was investigated. Experimental results show that the circuit leakage is a critical factor to the amplification of actuator voltage. The voltage ratio increases with increasing Bypass capacitance, but its increasing rate decreases.

Active and Passive Smart Structures and Integrated Systems 2014, 2014Co-Authors: Jinhao Qiu, Zhang Jin, Hong Nie, Li ChengAbstract:An unsymmetrical switch circuit is designed for semi-active control method based on synchronized switching damping principle of piezoelectric actuators. A Bypass Capacitor and an additional switch are used to realize unsymmetrical bipolar voltage.

Simulations were carried out to verify the design circuit and the theoretical results of the switched voltage. The voltage ratio increases with increasing Bypass capacitance, but its increasing rate decreases. The results show that large Bypass Capacitor is needed to realize a voltage ratio of 3, which is common in some piezoelectric actuator such as MFC.
