Abstract
The paper aims at evaluating the sliding mode control parameters used to tune a dynamic damper in the vibration reduction system. The effectiveness of the presented vibration reduction system and the power of the controlled voltage source supplying an electrodynamic linear motor have been analysed. The classical sliding mode control algorithm has been modified based on the analyses of results of calculation. The operation of the modified algorithm has been checked during a simulation. The proposed vibration reduction system was implemented on a laboratory stand. The measurement results have confirmed the effectiveness of the considered system.
Highlights
The antiresonance phenomenon in mechanical systems was used to design mass dampers
Vibration reduction systems with mass dampers are used in building structures such as tall buildings, masts, towers, bridges, sport arenas and in various machines to reduce the vibration of their subsystems
The aim of the paper is to propose new methodologies based on sliding mode control for control vibration reduction systems designed with the use of mass dampers
Summary
The antiresonance phenomenon in mechanical systems was used to design mass dampers. Such a damper was proposed by Den Hartog in the 1920s. Many damper types have appeared since both simple naturally introducing the antiresonance to vibroisolated systems, and with control subsystems.. Vibration reduction systems with mass dampers are used in building structures such as tall buildings, masts, towers, bridges, sport arenas and in various machines to reduce the vibration of their subsystems. Many building structures have mass damper systems to protect them against seismic actions and strong winds.
