目前在一些响应速度较快的系统中,用微处理机尤其是八位通用微处理机进行直接数字控制(DDC)以及实时监测时,较为突出的矛盾是运算速度不能满足采样间隔的要求。本文探讨了一种方法,它通过分解传递函数的系数,把运算化为最少次数的移位和加、减运算,来实现一个传递函数。提高了运算的速度,为DDC和监测提供了一种有效的手段。
At present, in some fast responding systems, the direct contradiction between direct digital control (DDC) and real-time monitoring using microprocessors, especially eight general-purpose microprocessors, is that computational speed can not meet the sampling interval requirements. This article explores a method that transforms a transfer function by decomposing the coefficients of the transfer function into the least number of shifts and additions and subtractions. Improve the speed of operation, and provide an effective means for DDC and monitoring.
