    摘要: A control scheme is provided for a power tool having a rotary shaft. The control scheme includes: monitoring parameters of a power tool during operation of the tool; evaluating a rotational condition of the tool about a longitudinal axis of the rotary shaft using a function defined as a linear combination of the monitored parameters; and initiating a protective operation to address the rotational condition of the tool based on an output of the function. In a simple form, the function is expressed in the form c0+c1*m1+c2*m2+ . . . +cn*mn, where (c0, c1, c2 . . . cn) are constants and (m1, m2 . . . mn) are the monitored parameters.
