To set 130 t/d CFB circulation fluidized bed boiler DCS automatic design as an example,The related adjustment system is designed based on its requirement for control system,load control order and realization of control system.

Application of fuzzy control in load control of controllable pitch propellers;

Load controller with gain of load control and peak load trimming section;

Fuzzy logic for load control of the grinding mill;

Two kind of control systems are designed by using the optimized control instruction of the characteristic of unbalance power grid in this paper.

By analyzing the basic function of each intelligent system in intelligent buildings and the effect in system integration, the paper discusses the daily and emergency condition, the concentration and discretization of control instruction, real-time and unreal-time in the operation of intelligent system.

The main characteristic, operation principle, timing and control instructions of intelligent LED/keyboard series of HD7279A are presented.

Before the ultrafined powder is collected,the newly equiped density test device can provide the signals of volume density deviation in the air current,then the signals are converted into control commands,which bring out the modification to vibration circuit.
