Nonlinear control for an uncertain electromagnetic actuator [PDF]
2018 IEEE Conference on Decision and Control (CDC), 2018 This paper presents the design of a nonlinear control law for a typical electromagnetic actuator system. Electromagnetic actuators are widely implemented in industrial applications, and especially as linear positioning system. In this work, we aim at taking into account a magnetic phenomenon that is usually neglected: flux fringing.
