sir
i want to know more about magnetic bearing.so kindly give more about magnetic bearing.[/align]

magnetic bearing is A control device for controlling displacement of a magnetically supported moving member according to a command,
comprising:
a feedback circuit for detecting the displacement of the moving member to control the moving member to ensure stability and robustness of the magnetic support in response to the detected displacement, the feedback circuit comprising a closed loop composed of a displacement detector receptive of an output from a displacement sensor, an integral compensator coupled to the displacement sensor, a phase advancing compensator coupled to the integral compensator, and an electrical power amplifier coupled to the phase advancing compensator for effecting the magnetic support; and a feed forward circuit having an input terminal receptive of a command and an output terminal connected to the feedback circuit, and cooperative with the feedback circuit without disturbing the stability and robustness of the magnetic support for controlling the displacement of the moving member according to the command.
