柔性梁内平衡模型降阶与主动控制的实验研究
Model Reduction and Active Control of a Flexible Beam Using Internal Balance Technique
摘要
Abstract
The internal balance technique was effective for model reduction in flexible structures, especially ones with dense frequencies. However, due to the difficulty in extracting internal balance modal coordinates from physical sensor readings, research so far on this topic has been mostly theoretic and little on experiment or engineering applications. The internal balance method theoretically as well as experimentally was studied, and further an active controller based on the reduction model was designed. The research works on a DSP TMS320F2812-based experiment system with a flexible beam and brings forward an approximating approach to access internal balance modal coordinates. Simulation and test results have proven the proposed approximating approach feasible and effective, and the designed controller successful in restraining the beam vibration.关键词
