Objective To research and make one kind of temperature controller based on fuzzy control algorithm, so that the temperature of electric cooker in lab can be controlled in high performance. Methods Based on the characteristics of open heat and temperature control of the electric cooker, including big inertia, pure time-delay, nonlinearity and susceptibility, the hardware and software were designed, fuzzy control algorithm was designed by Matlab, the simulated system was realistically designed in Simulink for adjustment and a new approach was practically put forward for optimization design of stabilization using online interpolation algorithm. Results The system had a dynamic performance of rapid response without overshooting, with the stabilization improved. The practical results basically accorded with the simulated one. Conclusion The fuzzy controller completely fits the electric cooker for open heat. It helps to save cost, increase heat efficiency, reduce energy consumption and improve experimental condition, and thus is worth popularizing in biomedical labs.
