Abstract

The invention relates to an ink amount controller based on nonlinear compensation control algorithm with calculating feedforward, comprising a central control unit, a motor driving module and an ink fountain body motor, wherein the central control unit comprises a single-chip machine module, a network transmission module and an AD sampling module, the AD sampling module is used for acquiring the current position information of the ink fountain body motor and transmits the position information to the single-chip machine module, then the network transmission module transmits the current position information of the ink fountain body motor to a main station PLC (Programmable Logic Controller) which transmits the position instruction signal of the motor to the single-chip machine module through the network transmission module, and the single-chip machine module calculates the required rotation angle of the ink fountain body motor by adopting the nonlinear compensation control algorithm with calculation feedforward and transmits the control signal to the motor driving module for driving the ink foundation body motor to move. Compared with the prior art, the ink amount controller has the advantages of independence from controlled object digital models, small calculating amount, strong interference suspension capacity, stable ink amount regulation, high ink amount regulating precision and the like.

Description

Technical field [0001] The invention relates to an ink volume controller, in particular to an ink volume controller based on a calculation feedforward nonlinear compensation control algorithm. Background technique [0002] Reasonably determining the amount of ink required is a prerequisite for ensuring printing quality. If the ink volume is too small, the printed graphics and text will be blurred due to insufficient ink volume, and a large number of dots will be lost; if the ink volume is too large, it will also cause paste and dot increase, which will seriously affect the reproducibility of the tone. Therefore, it is necessary to flexibly adjust the amount of ink quickly and accurately according to the printing area during the printing process. The ink volume controller is an indispensable controller in modern printing equipment. Its appearance greatly accelerates the adjustment speed of the printer during the printing process, thereby shortening the production cycle of the pro...
