The study and application of integrated control strategy

According to the object with strong time-delay and time-varying nonlinear property, a integrated control strategy of combining the improved frame of Smith prediction method with fuzzy inference and the conventional control is put forward in the paper. It is possible to realize effectively compensation of time-delay and inertia character of the controlled object on line and to improve adaptive ability and robustness of the control system. In addition, this method can overcome the fault of single control plan. It is applied to the main stream temperature in fossil fired power plant, the test result has proved the integrated control strategy, to integrate advanced control and intelligent control with conventional control for a controlled object, is a vary effective strategy.
