The analytical modelling and real time estimation of electromagnetic forces brings many challenges and in many situations, it is very difficult to develop an accurate model of force production. The present work describes an estimation of the actual forces generated by an electromagnetic actuator based on augmented Kalman filter.

A cantilever beam with end concentrated mass has been chosen as a vibrating system and an E–shaped laminated core with coils on the middle limb has been chosen as the electromagnetic exciter. The available analytical formulation has been chosen for the calculation of the generated forces which have been corrected using augmented Kalman filter.

The developed experimental setup has a mild steel beam of 150 mm length with a mass of 560 g at its tip and an E shaped lamination core with a stack thickness of 38 mm.
