Semi-Active Suspension Laboratory System
The paper describes the semi-active suspension laboratory system (SAS), built to demonstrate and test a number of control algorithms. The heart of the system is the automotive engineering damper with the restoring force controlled by magnetic field. We use in our apparatus the Lord 1097 magnetorheological (MR) damper manufactured by the American company. MR devices benefit from the ability of MR fluids to rapidly change rheological properties upon exposure to a magnetic field. The main advantage of the SAS is its portability as a demonstrative experimental rig to test control damping algorithms. The damped less oscillations are compared to the On-off damped oscillations of the apparatus. The MR damper provides an effective solution to SAS control in a variety of applications.
