| 摘 要： | 针对传统反电动势滑模观测器(SMO)抖振造成的永磁同步电机转子位置检测、转速估算不准确的问题,在传统反电动势SMO的基础上提出一种新型饱和函数SMO。构造反电动势状态观测方程,利用Lyapunov稳定性理论论证其收敛性;同时考虑观测器增益系数以及低通截止频率的给定,根据实时转速反馈选取合适的观测系数和低通滤波器的截止频率;在低通滤波器后增加卡尔曼滤波器滤除系统的测量噪声和测量误差,提高观测精度。对比仿真和试验结果,验证了新型饱和函数SMO算法的实用性和有效性。

| Abstract: | In view of this problem, a method of novel sliding mode observer (SMO) of saturation function for PMSM based on the analysis of the principle of the conventional SMO was proposed. The state observation equation of back electromotive force (EMF) was constructed, and Lyapunov stability theory was used to prove the convergence. Meanwhile, the given of observer gain coefficient and low pass cutoff frequency are considered. The observation coefficient and cut off frequency of low pass filter was selected according to realtime speed feedback. The Calman filter is added to remove the measurement noise and measurement error of the system. The simulation and experiment results verified improved new type of SMO of saturation function algorithm was effective and practical. |
