Intelligence control method and application for decomposing furnace

In order to overcome the control difficulties resulted from the characteristics of decomposing furnace, such as non-linear, time-varying and large time delay, a multi-mode intelligent control method is proposed in the paper by the combination of fuzzy control, Bang-Bang control, feed forward control, expert control and variable integral PID control. This control method through a multi-mode intelligent control rules automatically identify the different modes and select a appropriate control algorithm to correct variable integral PID control. Industrial applications show that the control system has good robustness, obtain good control results, and enable enterprises to achieve 3% coal saving and its comprehensive energy consumption reduced by 1.5%.
