要約(英語): This paper presents a new sensorless vector control method for permanent-magnet synchronous motors (PMSMs) that employs discrete-time high-frequency voltage injection. The frequency range of the injected voltage is almost the same as that of the pulse width modulation (PWM) carrier of the voltage command. This allows high-speed phase estimation and high-performance drive, and possibly low acoustic noise caused by the injected voltage. The current associated with the injected voltage, which has a frequency almost equal to the carrier frequency, must be analyzed in a discrete-time manner. This is because, a simple approximation of the continuous-time analysis of the high-frequency current cannot be applied in the range of the carrier frequency. Based on discrete-time analysis, this paper reconstructs the conventional rotor phase estimation methods using positive- and negative-phase high-frequency current correlation signals. The usefulness of the proposed method is verified through extensive experiments.
