Abstract

Cantilever beams have an important role in day to day life in bridges, towers, buildings and aircraft wings, making active vibration suppression a highly researched field. The purpose of this paper is to detail the design of fractional order PID controllers for smart beams. A novel tuning procedure is proposed based on solving a set of nonlinear complex equations that directly aim at reducing the resonant peak. The control parameters are computed through optimization techniques, making sure that the best ones are chosen. The practical stand was realized using magnet-coil approach and not piezoelectric actuators. The experimentally obtained vibration results prove that fractional order PID controllers can be used in practice to significantly reduce the amplitude and settling time of the vibrating system.
分数阶pi - λ - dμ控制器的振动抑制
悬臂梁在桥梁、塔楼、建筑物和飞机机翼的日常生活中发挥着重要作用,使主动振动抑制成为一个高度研究的领域。本文的目的是详细设计智能光束的分数阶PID控制器。提出了一种新的调谐方法,该方法基于求解一组非线性复方程,直接针对降低谐振峰。通过优化技术计算控制参数,确保选择最佳控制参数。实际支架采用磁线圈方式实现,不采用压电作动器。实验得到的振动结果证明,分数阶PID控制器可以在实际应用中显著降低振动系统的振幅和稳定时间。
