Abstract: This thesis introduces the development history and basic principle of internal model control,elaborates the design of IMC controller and proposes the way of Taylor progression PID parameter tuning based on internal model control.By MATLAB simulation for the heater temperature closed-loop control system based on IMC-PID,the effect of IMC-PID parameters tuning is compared with that of traditional PID parameters tuning,its better characteristics are demonstrated and the practical application value ...
