| Summary: | 碩士 === 清雲科技大學 === 機械工程研究所 === 100 === The main goal of this thesis is to develop a novel approach for vibration control on a piezoelectric smart flexible cantilever plate. This study will analyze such the dynamics of a flexible structure system with multiple degrees of freedom by using Euler-Lagrange formulation. The controller has two separate feedback loops for tracking and damping, and the vibration suppression controller is independent of position tracking control. This is done by using an intelligent fuzzy controller based on adaptive neuro-fuzzy inference system (ANFIS). In this research, ANFIS has been used to optimize the fuzzy IF-THEN rules and the membership functions to derive a more efficient fuzzy control. Experimental validation for such a structure demonstrates the effectiveness of the proposed controller as well as PD control. The broad range of problems discussed in this research will be found useful in civil, mechanical, and aerospace engineering, for flexible structures with multiple degree-of-freedom motion.
