摘要: This paper is about mechanical vibration absorption in a cantilever beam. accomplished by an active control scheme. The experimental set up consists of aluminum beam clamped to electrodynamical shaker. In that the main actuator piezoelectric patch and feedback signal obtained with small accelerometer. For purposes closed loop done via positive controller. this work modeled four element finite model. model also presented. Experimental validation And some results are shown numerical simulation as well platform.
