Control system for controlling a magnetic suspension system

A magnetic suspension system comprising:

• magnetic actuators configured to magnetically levitate an object,
• a position sensor system for generating position signals indicative of a position of the object with respect to a reference position of the object, and
• a control system for controlling electric currents of coils of the magnetic actuators based on the position signals,
• wherein the control system comprises controllers each being configured to control one or more of the magnetic actuators for magnetically levitating the object, wherein one of the controllers is configured to operate as a master controller and other one or ones of the controllers are configured to operate as one or more slave controllers, and the master controller is communicatively connected with one or more digital data transfer links to the one or more slave controllers, wherein digital data transferred via the one or more digital data transfer links is indicative of reference values of electric currents of coils of the magnetic actuators, the master controller being configured to control operation of the one or more slave controllers, and
• wherein each of the controllers comprises a control board configured to carry out computations related to magnetic levitation and replaceable power boards each being configured to supply electric current in accordance with a control signal received from the control board.
