摘要:
传统永磁同步电机无传感器控制方法中,常用的滑模观测器因存在抖振问题会导致转子位置及转速观测准确度下降,针对该问题提出一种基于互补滑模的改进观测器。基于永磁同步电机的数学模型设计了互补滑模观测器,基于Lyapunov 理论证明所设计观测器的稳定性。并引入卡尔曼滤波器消除传统反电动势滤波所产生的相位误差,以进一步提升转子位置及转速的观测性能。通过仿真实验对不同的运行工况进行了验证,结果表明所提方法能够有效消除抖振问题,提高观测精度。
Abstract:
In traditional sensorless control methods for permanent magnet synchronous motors, the chattering problem associated with commonly used sliding mode observers can lead to a decrease in the accuracy of rotor position and speed observation. To address this issue, an improved observer based on complementary sliding mode is proposed. A complementary sliding mode observer is designed based on the mathematical model of the permanent magnet synchronous motor, and its stability is proven using Lyapunov theory. Additionally, a Kalman filter is introduced to eliminate the phase error generated during the back electromotive force filtering process, further enhancing the observation performance of rotor position and speed. Simulation experiments validate that the proposed method effectively mitigates chattering and improves system observation accuracy under various operating conditions.
