Abstract

The invention relates to a method and a processor for a transforming width difference analog signal into a digital control model, belonging to the field of the signal transformation technology. The method comprises the following steps of: transforming a wavy analog signal with a width difference into a string waveform code, calculating movement velocity of an object represented by the original analog signal in a corresponding section by the string waveform code so as to determine a starting point waveform code, and substituting the movement velocity and the starting point waveform code into a digital control model function artificially set so as to calculate a digital control signal. The invention has the advantages that: the method can obtain an accurate feedback control starting point and a terminal point as well as a control manner between the starting point and the terminal point. The method and the processor provided by the invention are properly suitable for a feedback regulating movement state of an object in a variable rectilinear motion.

Description

technical field [0001] The invention belongs to the technical field of signal conversion, in particular to a method and a processor for adding width difference analog signals into artificially set digital control model functions to become digital control model signals. Background technique [0002] To perform feedback control on the moving state of the moving object, the electric signal of the moving state of the moving object can be obtained first, and the electric signal is used to feedback and control the moving state. If only the analog signal of the motion state can be obtained, any artificially set control model cannot be added to the analog signal, let alone an artificially set arbitrary control model related to the moving position point of the object. The method of controlling the motion state by feedback of the analog signal cannot achieve the effect of completely artificial ideal control. [0003] The analog signal cannot select a specific motion position point: t...
