Abstract

In this study, a sliding mode observer (SMO) based on high-frequency (HF) voltage signal injection and a phase-locked loop (PLL) is proposed for estimating the extended electromotive force (EEMF), rotor position, and rotor velocity of an interior permanent magnet synchronous machine (IPMSM). This approach addresses real-time estimation challenges associated with standard SMO and PLL at very low speeds and standstill. A reliable and accurate sensorless speed control system for IPMSM is then developed and implemented in real time using the proposed SMO and PLL, covering a wide range of speeds, including low-speed and standstill conditions. The SMO effectively estimates the EEMF, while the PLL extracts the rotor velocity and position based on these estimates. Compared to conventional SMO and PLL methods, real-time results from an 8-pole, 0.4 kW IPMSM demonstrate the superior efficiency of the proposed system.

设计并实时实现利用电压信号注入和 PLL 的滑模观测器，用于 IPMSMs 的无传感器控制

本研究提出了一种基于高频（HF）电压信号注入和锁相环（PLL）的滑模观测器（SMO），用于估计内部永磁同步电机（IPMSM）的扩展电动势（EEMF）、转子位置和转子速度。这种方法解决了标准 SMO 和 PLL 在极低速和静止状态下的实时估算难题。然后，利用所提出的 SMO 和 PLL，为 IPMSM 开发并实时实施了一个可靠、精确的无传感器速度控制系统，该系统覆盖了广泛的速度范围，包括低速和静止条件。SMO 可有效估计 EEMF，而 PLL 可根据这些估计值提取转子速度和位置。与传统的 SMO 和 PLL 方法相比，8 极、0.4 千瓦 IPMSM 的实时结果证明了所提系统的卓越效率。
