Sliding Mode Control of a Flexible Beam using Piezoceramic Actuators

摘要

This paper presents the sliding mode control scheme for vibration suppression of a flexible structure using piezoceramic actuators. The piezoceramic patches are bonded near the fixed end of flexible aluminum cantilever beam. The dynamic model of the flexible aluminum cantilever beam is derived. The sliding mode control is experimentally verified on a flexible beam using xPC Target real-time system, showing that it has satisfactory performance in vibration suppression. Experimental results demonstrate that the proposed sliding mode control can achieve effective vibration suppression results.
