A Three‐Stage Integrated Sliding Mode Observer‐Based Position Estimation Scheme for PMSM

Jun Cai, Yuhan Gu, Ying Yan, Adrian David Cheok et autres

ABSTRACT To further improve the position estimation performance of permanent magnet synchronous motor (PMSM) and reduce the high‐frequency chattering of the sliding mode observer (SMO)‐based position estimation strategy, this paper proposes a three‐stage integrated SMO‐based sensorless position estimation algorithm that integrates an …

Cost-Function Extremum Seeking Based Model Predictive Torque Control of PMSM With Sensorless Position Estimation

Jun Cai, Yuhan Gu, Zeyuan Liu, Shoujun Song

In this article, a cost-function extremum seeking-based model prediction torque control (CES-MPTC) method of permanent magnet synchronous motor with sensorless position estimation is proposed. First, as the predictive torque and flux linkage are the functions of theDQ-axis voltage components, once the partial …

A Survey of Phase-Locked Loop Technologies in Sensorless Position Estimation of Permanent Magnet Synchronous Motor Drives

Jun Cai, Yuhan Gu, Adrian David Cheok, Ying Yan

The phase-locked loop (PLL) algorithm uses the external input reference signal to control the frequency and phase of the internal oscillation signal of the loop; thus, the control signal and the internal signal can be synchronized to achieve the purpose of phase …
