Abstract
Fuzzy control rules can be converted into mathematical functions through fuzzy set theory and fuzzy reasoning theory, which can be easily combined with other physical laws to realize control strategies through computer software. At the same time, the fuzzy rules designed by expert experience can effectively control complex controlled objects, after actual debugging, its robustness and adaptability can easily meet the requirements. Combined with the fuzzy self-tuning PID control strategy, a fuzzy PID control system of the vehicle inverter is designed. Through the analysis of the inverter control system in the specific project, the mathematical model of the entire control system is obtained, and MATLAB simulation is carried out. The simulation results show that the fuzzy PID control system greatly improves the steady-state performance of the system, the output waveform distortion is small, and the harmonic content is low, which better meets the control requirements of the vehicle inverter.
