CONTROL OF AN ACTIVE DAMPER BASED ON
MAGNETO-SENSITIVE FLUID AND RUBBER
Magneto-sensitive (MS) fluids and rubbers are a class of smart materials whose mechanical properties change instantly by the application of a magnetic field. The damper based on MS fluids and rubber is one of the most promising new devices for structural vibration reduction. It is described by an original dynamical system with controlled viscosity and stiffness. The problems of the parametric control of damping and generation of harmonic oscillations for the presented dynamical system are solved by the Lyapunov method. All theoretical results are based on the theorem about asymptotic stability in reference to the part of variables as well as the Barbashin-Krasovski and Chetaev theorems.
