Active Feedback Vibration Suppression of a Flexible Steel Cantilever Beam Using Smart Materials

Considerable attentions have been devoted recently to active vibration control using intelligent materials as actuators. This paper presents results on active control schemes for vibration suppression of flexible steel cantilever beam with bonded piezoelectric actuators. The PZT patches are surface-bonded near the fixed end of flexible steel cantilever beam. Active vibration control methods such as strain rate feedback control (SRF) and positive position feedback control (PPF) are investigated and implemented using xPC target real-time system. Experimental results demonstrate that the SRF control and PPF control achieve effective vibration suppression results of steel cantilever beam
