چکیده
In this paper, for nonlinear, time-varying and delayed system, PID parameters self-tuning fuzzy control was applied to a level process. The method of using VC++ programming to realize fuzzy control algorithm and obtain the discrete fuzzy control table is proposed, which simplified the computing process greatly. Furthermore, combing the inquiry of fuzzy control table and PID function module in PLC, the bottom-layer of fuzzy control on PLC is realized. Simulation by M-language of MATLAB validates the effectiveness of PID parameters self-tuning fuzzy control system. Key-Words: Fuzzy PID parameters self-tuning, discrete fuzzy control table, fuzzy inference programming, PID function module, PLC, M-language
