Active control of vibration in small and medium amplitude range of elements in automotive systems

Abstract

In this paper two different visco-elastic suspensions active system with pneumatic cylinder, and semi-active system with piezoceramics, are presented. The active suspension controls the vibration in mediumamplitude range and low frequency excitation. The semi-active suppression system controls the vibration in the audio frequency range and small amplitudes. The main aim of proposed solutions is to decrease the amplitude of vibration in resonance of conventional, passive suspensions. Both systems are worked out, especially for the better protection of the human body against harmful sounds and vibrations.

Poly-optimization: a paradigm in engineering design in mechatronics

“…The vibro-isolation properties of such a suspension system can be shaped by appropriate selection of the controller settings. The description of the complete mathematical model and its experimental verification have been presented in the paper [8]. A dynamical behaviour of suspension system is described by the following state variables: a movement of the suspended mass x (Eq.…”
