Positioning control of linear motor for EMV via sliding mode servo control with variable switching hyper plane

摘要

In this paper, we propose a new positioning control method for the compact linear motor developed for an EMV (ElectroMagnetic engine Valve). This motor has a nonlinear property due to the detent force and the friction. We design a positioning controller using sliding mode servo control with variable switching hyper plane in order to realize the robust property against the nonlinear property and the high speed positioning. The effectiveness of the proposed controller is confirmed by some experiments.
