Abstract

This paper presents active vibration control of smart cantilever beam using poling tuned piezoelectric actuator. The vibrating response of piezo-laminated cantilever beam is modeled using a lumped parameter approach. The fuzzy logic controller is used to control the vibration and 49 rules have been established to develop the controller. Sensor voltage and derivative of sensor voltage are considered as inputs while the actuator voltage is considered as an output. Different piezoelectric materials are considered for analysis to improve the performance of the piezoelectric actuator layer using poling tuning phenomena which further enhances the control performance. In Poling tuning phenomena, poling is done at an angle due to which different piezoelectric strain coefficients i.e., transverse (d31 mode), longitudinal (d33 mode), and shear (d15 mode) are activated simultaneously and start contributing toward effective piezoelectric strain coefficient. The poling angle corresponding to the maximum magnitude of effective piezoelectric strain coefficient is called an optimized poling angle. Significant enhancement of 60.78% in control performance in PMN-0.42PT is observed at optimum poling angle of (Formula presented.) whereas, BT-NNb shows 36.75% improvement in control performance at an optimum poling angle (Formula presented.) On the other hand, PZT-7A shows a minimum improvement of 15.53% at optimum poling angle (Formula presented.).
