| 摘 要： | 永磁同步电机无速度传感器控制中,鉴于固定的噪声协方差阵不能同时满足动态和稳态的要求,通过引入一种变参数的自适应扩展卡尔曼滤波器(EKF),给出了一种永磁同步电机(PMSM)无速度传感器控制方案.以角加速度的值为选取依据,判断电机的运动状态,针对稳态过程和动态过程分别选定两组参数,以保证滤波器的快速性和稳定性,进而实现E...

| Abstract: | In the control of PMSM speed sensorless system,fixed noise covariance matrixes cannot satisfy the requirement of dynamic process and static process.By introducing a kind of variable parameter of adaptive EKF,a scheme of PMSM speed sensorless control was presented.With the value of the angular acceleration to judge the motor moving state,for static process and dynamic process two groups of parameters were given to ensure the rapidity and stability of the filter,and then realize the adaptive control of EKF.Th... |
