| Abstract: | According to a large dead-time and inertia of the control object of room temperature, a fuzzy self-tuning PID controller with smith predictor was designed. The mathematical model of the controlled plant was built, the structure and principle of predictive fuzzy PID controller were presented, and the fuzzy inference process was provided. The models of controllers were introduced and the simulation result was given. The simulation shows that the control system with proposed controller not only has a high controlling accuracy, but also has the characteristic of rapid adjustment with small overshoot. |
