摘要
This paper firstly introduced the principle and technological method of fuzzy self-tuning algorithm, and discussed related parameters and rules of the fuzzification, membership function, fuzzy rule and defuzzification in the fuzzy self-tuning algorithm. Then, two kinds of PID control methods were compared by the Simulink simulation platform, and the result showed that the input adaptability and anti-interference ability of fuzzy self-tuning controller of PID parameters were significantly better than those of fixed PID controller. Finally, the result was verified by the SPMIG welding test for aluminium alloy sheet with a thickness of 2mm, thus obtaining better welding effect.
