Abstract
This paper addresses real-time magnetic levitation control using the TMS320C31 Digital Signal Processing Starter Kit (DSK). A phase-lead controller is designed. The controller coefficients are then included in an assembly language program that implements the phase-lead controller. A MATLAB program is used to activate the phase-lead controller, calculate and plot the root locus of the control system. When the MATLAB program is run, it plots the root locus of the system on the PC screen, assembles the phase-lead controller assembly language program, and loads/runs the resulting executable file on the C31 DSK to achieve real-time control. Results show the system outputs are as expected with a phase-lead controller, with actual system outputs matching theoretical calculations.
