摘要：AbstractUsing an electromagnet as direct source of axial force generation is not yet very common in automotive clutch applications because of the inherently nonlinear dynamics. In this article a physically reasoned model is used to describe the electromagnetic clutch actuator's behavior and system Identification is carried out in order to design a model-based controller. Special attention is paid to the determination of the current-and position-dependent inductance. In addition, a flatness-based position controller is developed that enables smooth armature motion without introducing unwanted torque jerks. Experimental results obtained on an actuator test bench show the effectiveness of the proposed controller.
