To temperature control strategy of household variable frequency air conditioner,fuzzy control arithmetic was applied and the corresponding algorithm was designed.Then Matlab software was used to simulate the scheme.The results indicate that the control strategy presented has a better performance on time adjusting and control accuracy,compared with traditional fuzzy and PID control arithmetics.Combining the advantages of both fuzzy control and PID control,the hybrid control synthesizing parameter self adjusting fuzzy control and PID control was selected at last.
