Abstract

In this paper, Feedback Inc. model 33-210 lab-scale one degree-of-freedom (DOF) magnetic suspension system plant is used as a test bed for mechatronic sensing and control experimentation. First, a nonlinear mathematical model of the magnetic suspension system plant is linearized about a desired equilibrium position. The resulting linear model is used to design classical and optimal state feedback digital controllers to suspend a 21 gram hollow steel ball at a desired set-point and track reference position square-wave signals. The digital controllers are implemented using Texas Instruments TMS320C31 digital signal processor (DSP) based DSPACE DS1102 board and Simulinkreg.
