【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.更多还原
