Active vibration damping for manufacturing machines using additional cable mechanisms: conceptual design

Cable-based Reconfigurable Machines for Large Scale Manufacturing

Reconfigurability means low cost and short time to change machine configuration to meet application demands. Typical machining and positioning systems use hard actuators, like screws and pistons, and are built with slideways and hard frames. These components provide good stiffness, are well-proven, and can be packaged into modules to build reconfigurable machines. They are also relatively expen...

Active Vibration Damping of a Smart Flexible Structure Using Piezoelectric Transducers: H∞ Design and Experimental Results

This paper deals with active vibration control of a plate like smart flexible structure. This plate is equipped with several thin piezoelectric patches. Some of them are used as sensors and the others as actuators. They are optimally positioned and not collocated. The main goal of control is to reduce the most energetic vibrating modes. By using a state-space representation of a MIMO model of t...

Design of Additional Damping Controllers with Subsynchronous Oscillation Damping Effectiveness

When we research the suppression problem of subsynchronous oscillation based on time domain simulation method, we find the appropriate parameters for phase compensation and amplitude gaining links are important to the damping effect of the additional damping controllers, supplementary excitation damping controller(SEDC) and subsynchronous supplementary damping controller(SSDC). Some scholars at...

Field Programmable Gate Array Implementation of Active Control Laws for Multi-mode Vibration Damping

This paper investigate the possibility and effectiveness of multi-mode vibration control of a plate through real-time FPGA (Field Programmable Gate Array) implementation. This type of embedded system offers true parallel and high throughput computation abilities. The control object is an aluminum panel, clamped to a Perspex box’s upper side. Two types of control laws are studied. The first belo...
