Abstract:For cold area biological oxidation pretreatment intensive multistage differences in oxidation tank temperature control problems, this article through to a single oxidation groove heat exchange tube electric regulator using PSO to optimize the PID neural network control methods to protect the oxidation tank temperature control accuracy, on the basis of the multistage oxidation tank system USES speed dynamic compensation coordinated control method based on maximum error, speed dynamic compensation coordinated control model is set up, and carries on the simulation, the results show that the method can accurately control the temperature of the multistage oxidation groove, meet cold area special weather conditions of process requirement, the results of the study for cold area of biological metallurgy technology provides a new thought and method of precise control.
