This paper presents the local PD control strategy for radial Active Magnetic Bearing (AMB) designed with three electromagnets. It is the minimal configuration of actuators that allows to levitate the rotor in the electromagnetic field. The configuration of the laboratory test-rig, hardware components of the control system and description of developed algorithm is presented. Rapid prototyping environments with ability for dynamic reconfiguration that are used in the controllers design are described. The PD control algorithm as the minimal required closed loop strategy for rotor levitation is calculated and discussed to be applied in the presented control systems.
