With respect to the control of heat-sealing temperature of packaging plastic film, a type of automatic heat-sealing temperature control system was designed based on fuzzy adaptive PID control algo- rithm. The self-tuning of control parameters and the self-adjusting of control rules were realized by using variable un- iverse fuzzy PID. The control results were compared with those of traditional PID. The fuzzy PID control method could control the heating temperature in a more stable way than the tradit
