Abstract
A control system (1) for a magnetic bearing (3, 4). The control system (1) comprises a control loop (BR1) for the magnetic bearing. The control loop comprises a master control node (5) and at least two slave control nodes (6, 7). The slave control nodes (6, 7,) are connected in series by a first bidirectional data bus (8) of said system. A second bidirectional data bus (9) connects the control nodes (6, 7) situated at the ends of the control loop to one another. The master control node comprises transmitting means (10).
Claims14
A method for controlling a magnetic bearing, the method comprising:
- providing a control loop comprising a first bidirectional data bus, a second bidirectional data bus, a master control node, and at least two slave control nodes, the first bidirectional data bus connecting the master control node and the at least two slave control nodes in series, the second bidirectional data bus connecting two control nodes of the master control node and the at least two slave control nodes situated at each end of the control loop to one another, each slave control node controlling a different servocontrol axis of the magnetic bearing;
- the master control node transmitting a first data frame through the first data bus;
- and
- the master control node transmitting a second data frame through the second data bus, the first frame and the second frame being identical.
