为了提高直接转矩控制(DTC)系统定子磁链估计精度,降低电流、电压测量的随机误差,提出了一种基于扩展卡尔曼滤波(EKF)实现异步电机转子位置和速度估计的方法。扩展卡尔曼滤波器是建立在基于旋转坐标系下由定子电流、电压、转子转速和其它电机参量所构成的电机模型上,将定子电流、定子磁链、转速和转子角位置作为...
位置敏感探测器PSD(Position Sensitive Detector PSD)具有位置分辨精度高(可达1~2 μm)、输出实时性好(响应时间约几微秒)、系统简洁的特点,在位置探测及相关领域内获得了广泛的应用;但PSD的输出信号小,易受到电路噪声的影响,若要充分发挥其性能,则需要高精度、...
