基于全局快速终端滑模转速调节器的PMSM驱动系统模型预测电流控制
Model Predictive Current Control for PMSM Drive System Based on Global Fast Terminal Sliding Mode Speed Regulator
摘要
Abstract
We develop a global fast terminal sliding mode (GFTSM)-based model predictive current control (MPCC) for a three-phase permanent magnet synchronous motor (PMSM) drive system.To overcome load disturbance and parameter variation,we design a GFTSM-based speed regulator,and prove its stability and robustness.To reduce stator current ripples and improve control accuracy,we present the MPCC method to select the optimal voltage vector of a voltage source inverter.The resultant GFTSM-based MPCC PMSM drive system not only runs reliably and steadily but also has a satisfactory control effect for its torque and speed.Compared with two MPCC PMSM drive systems,namely,the PI-based regulator and the conventional sliding mode-based regulator,the GFTSM-based regulator possesses better dynamical performance and stronger robustness,as well as weaker chattering and a smaller total harmonic distortion index of three-phase stator currents.Simulation results validate the feasibility and effectiveness of the proposed scheme.关键词
