Decoupling control method for hot air speed and moisture removal negative pressure of cut tobacco dryer and storage medium

The invention discloses a decoupling control method for hot air speed and moisture removal negative pressure of a cut-tobacco dryer and a storage medium, and the method comprises the steps: when the cut-tobacco dryer enters a preheating or production stage mode, according to control variables outputted by a hot air speed control loop and a moisture removal negative pressure control loop under single closed-loop negative feedback PID control, controlling the hot air speed and the moisture removal negative pressure according to the control variables outputted by the hot air speed control loop and the moisture removal negative pressure control loop; whether the hot air speed control loop and the moisture removal negative pressure control loop enter a preset linearization area or not is judged; when the hot air speed control loop and the moisture removal negative pressure control loop enter a preset linearization area, a process identification method is utilized to obtain a static gain matrix of the cut tobacco d
