The traditional three-layer PE anticorrosion of steel pipeline is manual operation, which is limited by the complexity of the three-layer PE anticorrosion in the process and the low yield of finished products, and cannot meet the current manufacturing requirements. The rapid development of computer technology is beneficial to intelligentize the production process of three-layer PE anti-corrosion forming process. With some advanced soft-sensing technology and corresponding computer technology, each stage of pipeline PE anti-corrosion molding production is modeled, and based on its non-linear, large-delay and multi-disturbance system characteristics, an intelligent segmentation control scheme is proposed in this paper, especially with the traditional PID algorithm and feedforward feedback control algorithm. At the same time, a strong coupling optimization algorithm is proposed to optimize the control system proposed in this paper. Finally, based on the anti-corrosion data of an oil pipeline, this paper has been verified and analyzed. The experimental results show that the algorithm is superior.
