Abstract :
The conventional PID control can not receive satisfactory results to liquid level systems, because time delay always exists in these systems. Therefore, a kind of self-adaptive fuzzy Smith control is constructed by combining the merits of Smith predictor and fuzzy PID control, and applied to liquid level systems. The simulation results show that the proposed method can work satisfactorily.
