Abstract

The invention discloses a method and processor for changing a peak difference analog signal to a digital control model, belonging to the technical field of signal conversion. The method comprises the following steps of: changing an analog signal of which the waveform has peak difference into a string of waveform codes; calculating the change speed of the original analog signal of the corresponding segment by use of the string of waveform codes; determining the start point waveform code; and substituting the change speed and the start point waveform code into the manually set digital control model function to calculate a digital control signal. Through the invention, the feedback control start point and end point as well as the control mode between the start point and the end point can be accurately obtained, and the feedback control digital control model function can be manually changed to the optimal start point, end point and control mode between the start point and the end point. The method and processor disclosed by the invention are best suitable for the feedback regulation of the motion state for the object in variable-speed circular motion.

Description

technical field [0001] The invention belongs to the technical field of signal conversion, and in particular relates to a method and a processor for adding a peak difference analog signal into an artificially set digital control model function to become a digital control model signal. 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 po...
