Title:
IMPROVED ACTIVE MAGNETIC BEARING CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2015010716
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent instability by eliminating axial disturbance of an axial magnetic bearing without increasing costs.SOLUTION: A control device for controlling a position of a rotor 10A supported by active magnetic bearings comprises: a trajectory planning module 12 for generating a requested position, speed and acceleration; a first correction circuit 18 for generating a first command signal according to a difference between a position feedback value and a speed feedback value by an observer 20; a feedforward controller 14 for generating a second command signal according to a computation of the position, speed and acceleration; an adder 16 for adding the first and second command signals and generating a third command signal for electromagnets; and a second correction circuit 28 for generating voltage command signals for power amplifiers which control a current flowing in electromagnet coils of the active magnetic bearings according to a difference between flux command signals and flux values by the observer.
