Control-system development of a high-speed electromagnetic actuator in consideration of the delay in the control force

A control system for a high-speed electromagnetic actuator contains the problems of electromagnetic nonlinearity, a rising current lag, and a lag in the control force caused by an eddy current. In this paper, we conduct a simulation and a control experiment that take those influences into account. Our results confirmed the effectiveness of the control method, which provides compensation for the nonlinearity of the control force, the rising current lag and the control force lag.
