A neural-network (NN)-based active control system was proposed to reduce the low frequency noise radiation of the simply supported flexible plate. Feedback control system was built, in which neural network controller (NNC) and neural network identifier (NNI) were applied. Multi-frequency control in frequency domain was achieved by simulation through the NN-based control systems. A pre-testing experiment of the control system on a real simply supported plate was conducted. The NN-based control algorithm was shown to perform effectively. These works lay a solid foundation for the active vibration control of mechanical structures.

Vibration suppression of speed-controlled robots with nonlinear control

《机械工程前沿(英文)》 2016年 第11卷 第2期 页码 204-212 doi: 10.1007/s11465-016-0380-3
In this paper, a simple nonlinear control strategy for the simultaneous position tracking and vibration damping of robots is presented. The control is developed for devices actuated by speed-controlled servo drives. The conditions for the asymptotic stability of the closed-loop system are derived by ensuring its passivity. The capability of achieving improved trajectory tracking and vibration suppression is shown through experimental tests conducted on a three-axis Cartesian robot. The control is aimed to be compatible with most industrial applications given the simplicity of implementation, the reduced computational requirements, and the use of joint position as the only measured signal.

Vibration control of a structure using Magneto-Rheological grease damper

This paper describes an application study of Magneto-Rheological (MR) grease damper to a structure with three stories. MR fluid is known as one of successful smart materials whose rheological properties can be varied by magnetic field strength, and has been applied to various kinds of device such as dampers, clutches, engine mounts, etc. However, ferromagnetic particles dispersed in MR fluid settle out of the suspension after a certain interval due to the density difference between the particles and their career fluid. To overcome this defect, we have developed a new type of controllable working fluid using grease as the career of magnetic particles. Network of thickener in grease is expected to hold the magnetic particles and prevent them from settled down. No or little sedimentation was observed in MR grease whose characteristics could be controlled by the magnetic field strength. MR grease was introduced into a cylindrical damper and its performance was studied. As a result, it was confirmed that the damping force of MR grease damper could be controlled by the applied electric current to the coil in the cylinder of damper. Furthermore, vibration response of a three-story model structure equipped with MR grease damper was investigated experimentally, and it was shown that MR grease damper worked effectively as a semi-active damper.

主动式振动控制技术通常拥有优异的控制性能,但其在大型结构应用中常常伴随着巨大的能耗,使得我们在实际工程应用中较难看到它的身影。针对这一问题,本文创新性地提出了一种全新的解决方案:自供能的主动式振动控制系统;并针对性地对其拓扑设计、工作原理、能量流动等方面进行了介绍。通过对振动过程中能量流动的详细分析,我们进一步确认了系统的自供能可行性。此外,我们于实验室内搭建了一套所提出的自供能主动式控制系统,并成功将其应用到一个小型主动隔振台上。通过对解析、数值和实验结果的一系列探究,这个新型系统的有效性与可行性得到了充分的印证。预期这套新型装置可以非常容易地推广到其他多种工程领域中来实现所期望的主动控制效果。

Piezoelectric materials have become the most attractive functional materials for sensors and actuators in smart structures because they can directly convert mechanical energy to electrical energy and vise versa. They have excellent electromechanical coupling characteristics and excellent frequency response.
