| 摘 要： | 在分析直驱型永磁同步风力发电机数学模型的基础上,确定了一种基于滑模观测器和扩展卡尔曼滤波的转子位置和转速估计方法,并给出了系统控制策略.针对内埋式永磁同步电机直轴和交轴电感差别较大的特点,采用两相静止坐标系下的基于扩展反电动势的永磁同步电机滑模观测模型,并将耦合项作为扰动量进行解耦计算.采用卡尔曼滤波器以便滤除估计的扩展反电动势测量噪声分量,并增强其对于系统扰动和参数变化的鲁棒性.采用三相锁相环进行转子位置角和转速的提取.仿真和实验结果表明:该方法可以快速准确地得到转子位置和转速信息并应用于系统控制.

| Abstract: | Sliding mode observer and extended Kalman filter were used to estimate the rotor position and velocity based on the mathematical model of permanent synchronous magnet synchronous generator(PMSG).Because interior PMSG has unequal d-axis inductance and q-axis inductance,an extended electromotive force sliding observer model on the stationary reference frame was adopted,and the discrete decoupling calculation model was derived.Extended Kalman filter was used to filter the operational noises and to increase the... |
