中文摘要
      本文提出一种高阶非奇异终端滑模观测器, 用来估计永磁同步电机控制系统的转子位置和转速. 采用高阶非奇异终端滑模观测器, 使得控制系统不必外加低通滤波器, 就可获得平滑的反电动势估计值, 进而, 根据反电动势方程, 求解出转子位置和转速. 和传统滑模观测器相比, 高阶非奇异终端滑模观测器避免了反电动势估计值的相位滞后, 提高了转子位置和转速的观测精度. 仿真结果表明, 高阶非奇异终端滑模观测器具有快速收敛性及更高的跟踪精度, 同时消除了系统的抖振.
英文摘要
      We proposed a higher-order nonsingular terminal-sliding-mode(NTSM) observer for estimating the rotor position and speed of a permanent-magnet synchronous motor(PMSM) for its control system. This observer produces a smooth estimate of the back electromotive-force(EMF), without the need of an additional low-pass filter. Solving the equation of the back EMF, we obtain the position and the speed of the rotor. Compared with the conventional sliding mode observer, the high-order NTSM observer avoids the phase lag in the back EMF signals, thus improving the estimation precision of the rotor position and speed. Simulation results show that high-order NTSM observer provides fast convergence and high precision in position tacking with less oscillation.
