Abstract:

The current control system of dyeing machines has such drawbacks as single control mode, low degree of automation, and great consumption of water and power. Therefore, a novel control system is proposed, which applies PLC and configuration technique along with frequency conversion and intelligent PID, realizing discrete control and solving the above problems with improvement in real-time control. The experiments demonstrated that the modified system simplifies the production process, standardizes the operating process, and enhances levelness and quality of the dyed fabrics. With incorporation of PID control algorithm, the control system is characterized by good response, high precision, energy-saving and cost-reducing, pollution cut and efficiency enhancement.
