In this paper two nonlinear control methods are proposed to regulate vibration of flexible beam with piezoelectric actuator. The purpose of regulation is achieved by two nonlinear control methods: back-stepping and Adaptive sliding mode. The performance of the system by using the above-mentioned control methods is compared. Experimental results verified the effectiveness of adaptive sliding mode and back-stepping controllers. From the experimental results, the backstepping control system suppresses vibration in 5 seconds whiles smooth compensator suppresses in 10 seconds along with chattering phenomenon. Therefore, the back-stepping control system more accurately attenuates vibration of the beam.
