One-step scouring and bleaching of cotton fabrics in the lye of PID control system

This article describes the one-step scouring and bleaching of cotton fabrics in the PID control lye, the issue is the first Ministry of Science and Industrial Technology Innovation Alliance program sub-topics; it is also Tianjin Science and Technology sub-project issues. These implements (1) One-step scouring and bleaching, significant time savings. (2) Multi-sensor data fusion technology is adopted, the test data results of the three detecting device will be fusion, improve the accuracy of the detection data, the system dynamic performance and control accuracy. (3) Smart sub-processes and non-linear processing are adapted, the inference detection signal agencies to achieve a smooth transition, checking and correction. (4) Smart follow, even with the decoupling control technology are adapted, the reasoning sector in achieving the following level of each tank, even, once again realized the liquid level and flow decoupling. The system has been running at the production site.
