摘要
The electromagnetic actuators are widely used in the industry due to their simple structure, force characteristics, and low manufacturing costs. However, from control point of view, they are nonlinear systems. In this brief, clustering-based system identification experiments as well as a piecewise mathematical model are described. Furthermore, a model-based fault detection and isolation of the actuator is presented, when the armature movement is sensed indirectly, by sensing only the armature current.
