A multi-phase Hall signal rotating speed calculation optimization method comprehensively considers Hall device defects, signal burrs and abnormal conditions of a signal acquisition and processing circuit, and adopts a method of longitudinally and independently comparing and screening out outliers of a single Hall signal and transversely and mutually comparing and screening out constant values of multi-phase Hall signals to obtain a real rotating speed for closed-loop control. The optimal rotating speed can be effectively selected from the multi-phase Hall signals, the actual rotating speed of the motor is accurately calculated when the Hall signals break down, and the correctness of closed-loop control of the rotating speed is guaranteed.

    一种多相霍尔信号转速计算优化方法,综合考虑了霍尔器件缺陷、信号毛刺、信号采集和处理电路异常情况,采用单个霍尔信号纵向独立比较筛除野值、多相霍尔信号横向互相比较筛除常值的方法,得到可以用于闭环控制的真实转速,能够有效的从多相霍尔信号中选择最优转速,在发生霍尔信号故障时准确地计算电机实际转速,保证转速闭环控制的正确性。
