The paper deals with system identification and robust control of an electromagnetic actuator. There are many practical applications where this type of electromagnetic actuator is used : electromagnetic valve actuators, magnetic levitation, active magnetic bearings, etc. The investigated system is open loop unstable, nonlinear, and it has a restricted equilibrium region. A single input, single output analytical model and system identification experiments are presented with emphasis on the design procedure of an H_∝ controller. The obtained experimental results demonstrate that the controller design problem can be successfully handled within the framework of robust control.
