| Abstract: | In order to control the titration precision of staining agent for the printing and dyeing industry more quickly and accurately, The application of PLC - based servo control system in automatic dropping ma- chine to improve its titration precision was preliminarily investigated. According to the principle of servo con- trol the basic configuration of the titration precision control, the free communication between electronic scale and PLC, and the titration control algorithm were designed. The relevant experiments were carried out and an- alyzed. Experimental results showed that with the repeatedly closed loop control the control algorithm could make the titration precision reach ±0.
