Abstract: A circuit for converting a square wave to an average value in real time is provided to estimate a distance easily between a stator of an electromagnet and a moving member by averaging the square wave from a waveform with a variable duty ratio. A compares(100) compares a square input signal with a reference signal and generates a logic level converting signal. An FPGA(Field Programmable Gate Array)(120) includes a divider, a control signal generator, and a pulse counter. The control signal generator receives the logic level converting signal and a reference clock and generates a control signal. The pulse counter receives a clock signal and supplies a counted result to a multiplier under the control of the control signal. A first sample and hold unit(130) processes the square input signal and generates a first sample and hold signal according to the control signal. The multiplier(140) multiplies the counter result by the first sample and hold signal. A second sample and hold unit(150) processes an output from the multiplier to generate a second sample and hold signal according to the control signal. An adder(160) adds the second sample and hold signal to the input signal. A third sample and hold unit(170) processes the output from the adder to generate a third sample and hold signal.

본 발명에서는 각 코너에 T자형 레일을 따라 마그네트를 3개 배치하되, y 방향의 마그네트의 코일 2개 중 하나를 x 방향의 마그네트의 코일과 연결함으로써, 마그네트, 안내제어기 및 초퍼의 코너당 채널수가 2개가 되어 전체 채널수가 T자형 방식의 총 12개에서 총 8개로 줄었다. 그 결과, x 방향의 외란이 발생할 때, y 방향의 갭은 영향을 주지 않으면서 x 방향의 갭을 담당 안내제어기에 의해 제어될 수 있고, 또한, y 방향의 외란에 대해서도 x 방향의 갭에 영향을 주지 않으면서 y 방향의 갭을 일정하게 유지할 수 있게 된다. 또한, 제어 채널수가 줄어들어 시스템의 신뢰도가 올라가고 시스템 단가도 낮아지는 장점이 있다.
