A non-contact vibration measurement and control system for a piezoelectric-patched flexible cantilever plate is presented, using laser displacement sensors. Two laser displacement sensors are utilized to detect the deflection information of the two corners of the end of the flexible board, due to its high measurement accuracy for the small amplitude residual vibration. The vibrations of the first bending and torsional mode of the flexible plate can be extracted from the combined information. To achieve a desirable performance for the active vibration control, a kind of sliding mode predictive control strategy is developed to damp the vibration quickly. Simulation of the controller on bending and torsional vibration is conducted, based on the model built with finite element method. Furthermore, a piezoelectric flexible cantilever plate experimental setup is constructed. Experiments are conducted. The results of simulation and experiment both demonstrate the effectiveness of presented control scheme, compared with proportional and derivative control; the sliding mode predictive control can attenuate the vibration more quickly, particularly for the small amplitude residual vibration.

This paper describes the control methods, computer simulation and experimental results on the vibration control of the loader arm which is composed of a horizontal slider and a pendulum-type arm suspended from it. In order to achieve high-speed driving and accurate positioning of the loader arm without residual vibration, one of the software-cam curves, termed the ""modified sine curve,"" was applied to drive the loader. The cam curve was described numerically on a personal computer. Three control methods together with highgain feedback control are proposed, in which the path and velocity of the slider and the swing angle of the arm are controlled according to the prescribed software curves. Experimental results show that driving of the loader with such a software curve and control of it under the limitation of the maximum swing angle of the arm are very effective for rejection of residual vibration and accurate positioning of the loader.
