A double-deck fuzzy control system that control bed temperature of circulating fluidized bed boiler is designed in the paper,First floor is the PID controller,second floor is the fuzzy control that is used to modify the parameter of PID controller.

Based on analyzing the current situation of urban traffic signal control,a two-stage fuzzy control system for single intersection was designed in this paper.

After analyzing the city-traffic developments, the grade crossings control theoryand its method of evaluation, the paper designs a traffic signal two-stage fuzzy controlsystem for single intersection.

With the emphasis placed on the design of the two-stage fuzzy controller, the scheme of the fuzzy control system design is given.
