| Abstract: | A self-adaptive intelligent fuzzy-Smith control strategy is presented to improve the steady- state accuracy and self-adaptive ability. The fuzzy-Smith controller is used in a lower level and a self-adaptive method is used to make an on-line adjustment of both quantitative factors and scale factors in a supervisory level. Furthermore, the intelligent integrator is adjusted according to the deviation and the rate of change in deviation. Simulation results show that the proposed strategy is superior to the conventional fuzzy-Smith controller and is effective in controlling the time-varying processes with large time-delay. |
