Abstract

Digital control laws are implemented on an active magnetic bearing system with DSP. The results of tests using a experimental apparatus are (1) in a case that conventional PID, PIDD2 controls are employed, implemention of digital control law has similar characteristics to that of analogue control law. (2)The experiments reveal the results that the dynamic compensation based on the observer may be better than that of the other conventional controllers.
