| Abstract: | A new type of fuzzy variable-coefficient PID controller was discussed. By using fuzzy reasoning rules, fuzzy tables for PID parameters were obtained, and the parameters of PID algorithm can be modified on line by looking up these tables. This method has ability to resist the time-varying of system parameters, it is simple enough for real-time control and can be easily used by micro-processor based controller. It is used for the temperature control of injection machine material canister, the experimental results show that the fuzzy variable-coefficient PID controller has good performance in both dynamic and static state, and is more robust than normal PID controller. |
