This paper describes a novel method for current detection in sensorless control using high-frequency voltage injection. The proposed method adopts a low-pass filter to prevent ringing. Generally, reactive current cannot be detected using a DC filter; however the proposed method permits detection via voltage injection. High responsiveness and a simple construction have been achieved using the method. Simulation results indicate that active and reactive currents can be reconstructed using a single shunt current; the experimental results indicate that the proposed method can be applied to a motor drive without lowering the performance, unlike when using a current sensor.

“…Through the above assumptions, in order to simplify the mathematical model of PMSM and realize sensorless closedloop control, correlation transformation must be carried out. Before transformation, the coordinate systems used in the PMSM control principle include the ABC three-phase coordinate system, the αβ two-phase stationary coordinate system, and the dq twophase rotating coordinate system (Kawabata et al, 2014). The specific positional relationship of the three-coordinate systems is shown in Figure 1.…”

In order to reduce the chattering caused by the discontinuity of the control function in the traditional sliding mode observer (SMO), this article proposes a sliding mode observer with phase-locked loop (PLL) to estimate the speed and position of the rotor. The back electromotive force (EMF) of a permanent magnet synchronous motor (PMSM) in a static coordinate system is accurately estimated by SMO, and then, PLL is constructed to combine the observed rotor position angle and back EMF to compensate the phase lag in angle estimation so as to obtain a more accurate speed. It solves the problems of poor robustness and complex algorithms in the traditional SMO prediction algorithm. The simulation results show that the SMO with PLL can effectively reduce the system chattering and effectively improve the accuracy of rotor speed and position estimation.
