title = "A Predict Current and Position Compensation Method for PMSM Sensorless Control Under Low Carrier Ratio",
abstract = "The performance of the permanent magnet synchronous motor (PMSM) sensorless control system is limited in the case of the low carrier ratio such as high-power transmission systems. This work analyzes the main factors that cause system delay under low carrier ratio. A linear current prediction method base on volt-second equilibrium principle is proposed to solve the sampling filter and inverter nonlinear delay. Meanwhile, a self-adjustive position compensation is obtained through a PI controller based on the dq-axis voltage error to further suppress the digital control delay. On this basis, a sensorless field oriented control system is built based on a model reference adaptive system. Finally, a 1.5-kW SPMSM is tested to verify the feasibility of the proposed method.",
