Design of Temperature Controller for Heating Furnace in Oil Field

The temperature controller is an important part of the control system design of the crude oil heating furnace. the traditional PID control is usually used in temperature control, but it can not effectively overcome the impact by the interference, load change and the parameters change of system and other factors. Based on the relationship between rules factor α and the error E , meanwhile, taking into account the change of error r rate EC, the temperature controller is designed adaptive fuzzy control with variable slope. It greatly enhances the robustness of the system. By field application, works well.
