A Comparison of Active and Semi-Active Sliding Mode Controllers Applied in Vibration Reduction Systems

Abstract:

The paper presents active and semi-active vibration reduction systems applying sliding mode control systems. Calculations were completed for a laboratory system with two masses moving in a vertical direction. Support of the system is connected with the moving part of the exciter. The proposed system may be a simple model of many vibroisolated objects. In order to apply the control system of vibrations in the suspension of the upper mass, an actuator was implemented together with a spring. The role of the actuator was played by a linear inductive motor.Active and semi-active sliding mode controllers are proposed for the vibration reduction system. Theoretical analysis focused on applying of the sliding mode control in this system was carried out and, moreover, conditions to be met by the controllers were determined. The results of simulations and experiments are presented in tables and plots.
