摘要： Systems, methods, and computer-readable media are disclosed for error-compensated counting of Hall states for motor position feedback and/or commutation. An indicated Hall state is detected by digital Hall state sensors and a duration of the Hall state is compared to a specified time period. When the duration exceeds the specified time period, the indicated Hall state is compared to one or more valid Hall states and a position counter is changed for valid states. When the indicated Hall state is invalid, the position counter is not changed. The Hall state sensors may be connected to logic means and may detect the position of a rotor of a permanent magnet motor relative to a stator. When noise induces a change in an indicated Hall state, corresponding noise-induced effects on the position counter may be may be removed through error-compensated counting.

摘要翻译： 公开了用于马达位置反馈和/或换向的霍尔状态的误差补偿计数的系统，方法和计算机可读介质。 通过数字霍尔状态传感器检测到指示的霍尔状态，并将霍尔状态的持续时间与指定的时间段进行比较。 当持续时间超过规定的时间段时，将指示的霍尔状态与一个或多个有效的霍尔状态进行比较，并且针对有效状态改变位置计数器。 当指示的霍尔状态无效时，位置计数器不变。 霍尔状态传感器可以连接到逻辑装置，并且可以检测永磁电动机相对于定子的转子的位置。 当噪声引起指示霍尔状态的变化时，可能通过误差补偿计数来消除对位置计数器的相应的噪声引起的影响。
