Abstract
In this paper, a novel magnetic actuator named Linear Magnetic Actuator (LMA) is proposed, designed and fabricated for applications such as active magnetic bearing systems to deal with vibration problems in rotating machines. The LMA actuator is constructed from a moving body called ‘mover’ and three driving parts which drive the mover. Real-time experiments on the LMA have been conducted to derive a mathematical model for this actuator to investigate the generated electro-magnetic force as well as further research. The modeling results in a comparison with the actual performance show that the electro-magnetic force varied symmetrically with the mover motion defined by the applied current. Furthermore, an advanced trajectory controller — online tuning fuzzy PID controller has been designed for the LMA in order to improve the working performance. Finally, real-time experiments have been carried out to investigate the tracking performance of the designed LMA control system. The experimental results prove that the LMA driven by the proposed controller could track the desired trajectories with high accuracy.
