The Effect of Controllers on the Dynamic Behaviour of a Rotor Supported on Active Magnetic Bearings

A rotor system supported on active magnetic bearings (AMB) is an unstable system, a control system must be installed in order to realize the system stability. The controller has a great effect on the dynamic behavior of a rotor supported on the AMBs. The basic principles of PD controller, direct fuzzy controller, fuzzy PD controller and controller were introduced, these controllers were then realized in the d-SPACE control platform, and applied to a rigid rotor on the AMBs. The performances of these four controllers, such as step response, tracking a sinusoidal reference signal and simulation rotating debugging, were experimentally measured. Some conclusions can be gotten through the experiments.
