【摘要】 位置差分数字测速传递函数 ,直接影响按连续系统设计法设计的速度回路校正环节的有效性。通过本文推导和仿真验证表明数字测速传递函数等效为一个微分和惯性环节的组合更为合理 ,而不是文献 [1 ]、[2 ]等所等效的纯延迟环节。文章给出了满足等效的工程条件。

【Abstract】 The transfer function of speed measuremet realized by position differential in digital mode affects the controller′s effects directly when design the controller in continuous system method. Through deduction and emulation verification, this paper shows that the transfer function of speed measurement realized by position differential in digital mode is equal to a combination of a differential part and an inertia part, and it is more reasonable than to a pure delay part in reference 2 and 3. And also the engineering condition that the transfer function of speed measuring realized by position differential in digital mode is equal to a combination of a differential part and an inertia part is offered.
