Abstract

The influence of non-uniform magnetic field on the beam with magnetorheological fluid is used to build the vibration control algorithms. A special laboratory stand with appropriate electromagnet was built to test free and forced vibrations of the beam with and without control. Experiments were done to determine the stiffness and damping parameters of the beam for various currents flowing in electromagnet coils. A vibration control algorithm was proposed, based on the system identification data and using the averaging technique of nonlinear system analysis.
