In sensorless EMS, high frequency is injected into the system by using a switching power amplifier. This results in a triangular high frequency waveform for current. Slope Measurement of such waveform requires high computational resources as well as a knowledge about duty cycle variation of switching amplifier. A new method has been proposed that makes use of the high resolution-single slope detection to compensate for the duty cycle variation by exactly controlling the timings of the gate signals for a switching amplifier without the use of a voltage sensor or a dedicated sense cycle as was done in recent preceding works. The proposed method has been verified by numerical simulations. Prospective practical problems are also discussed in detail\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e要約(英語): \u003c\/strong\u003eIn this paper, air gap sensorless (self-sensing) electromagnetic levitation (EMS) control using current ripple slope measurement has been investigated.
