Active magnetic bearings (AMB) are unstable by their nature and are used in very
high-speed applications, therefore the design and implementation of a suitable control system
for such devices requires extensive investigation. In this paper the AMB control problem is
treated and design method of proportional plus derivative plus integral (PID) control system is
proposed using the two degrees of freedom method. The designed PID control system is
simulated and tested using MATLAB/Simulink, and some practical effects are investigated
