In drying process of tobacco industry, the export moisture always has performance with large time delay and strong nonlinearity. Also, disturbance factors exist in this process. At present, traditional PID controller is mostly applied in this process and it has problems such as large steady-state error and long response time, which influence the final quality of tobacco. In response, combined integrating controller is introduced and replaces the role of traditional PID controller in tobacco drying process. Meanwhile, dual control is introduced and combined integrating controller is applied in this strategy. The simulation result shows that the control performance of this new kind of control strategy is superior to the traditional PID controller. Its performance has less steady-state error and prompt response. It proves that combined integrating controller has excellent dynamic performance and robustness when applied in dual control system. Finally, the new kind of dual control strategy has been successfully applied in the moisture control of the tobacco drying process in the tobacco industry.
