Abstract

In this paper an adaptive finite impulse response (FIR) filter based control scheme is proposed which is employed for position tracking problem of a magnetic levitation system. The adaptive filters are designed on-line as approximate inverse system. At the first step, a PID controller is implemented to stabilize the position of a magnetically levitated ferric ball at a certain position, and then an adaptive FIR filter is incorporated in the loop to improve the stability of the closed loop. A second adaptive FIR filter is introduced to improve the tracking properties. The use of inherently stable adaptive FIR filters has guaranteed a stable controller. Experimental results are included to highlight the excellent position tracking performance of the system.
