Cascade Control System

Steam boiler supplies steam of certain quality in industry process according to the changes of load. It is important of most power plants and has been concerned with analyzing power system dynamics in various works. Drum water level is one of the main processes in the boiler. Because of the phenomenon of false water level, three measurement signals including drum water level, water supply flow and steam flow are introduced. In this paper three impulses Cascade control system with fuzzy PID control is presented, and simulation is performed based on MATLAB.

Factors Affecting

Medium and Small boilers, which are widely used, are common power equipments in power plants, Smelters, and chemical plants, and important to the safety and production of enterprises. In this paper, the main factors affecting the changing industrial boiler water level have been analyzed, and relevant control theory been studied. A cascade three-impulse supply water Fuzzy-PID control system and the implement of Fuzzy-PID control formula based on IPC and PLC have been introduced .The results of the simulation indicated that the design can overcome the illusive water level and can improve the performance of the system obviously. The cascade three-element feedback control system using IPC and PLC as the center control unit, combining the fuzzy control with the conventional PID control, obtains both virtues of the high precision of PID and the flexibility and adaptability of the fuzzy control.

Self Adaptive

As liquid level cascade system has the character the issue of non-linearity ,time variability and the overshoot,tradition PID control can not meet the requirement of precise molding system. So devise a self-_ adaptive fuzzy PID control .A self-_ adaptive fuzzy PID control combined PID to control calculate way and faintness to control the advantage of method, this text permits water tank to carry on mathematics model to design the double permit a water tank liquid misty PID string class control system. Matlab/Simulink and fuzzy logic toolbox are simulated to the single loop PID control system,the cascade control system and the cascade control system based on fuzzy self-tuning PID were simulated with Simulink. The analysis and simulation results indicate that the character issue of non-linearity ,time variability and the overshoot of the liquid level cascade control system based on a self-_ adaptive fuzzy PID controller are superior to previous of two methods.

The Subject

Boiler drum water level control system is hard to develop practical mathematical model and has nonlinear, stable and delay characteristics. The traditional boiler drum water level control often uses three impulse PID control method. The existing problem of ordinary PID control strategy is: once good parameter setting, it is hard to adapt to the change of the operation of the system dynamic greatly. In order to solve the problems of the above, the research object of the subject is a certain 120 t/h boiler steam capacity, the boiler drum water level control system is designed, and the control strategies are studied. In order to obtain better contrast, the ordinary PID controller and Fuzzy controller are designed, and the control strategies of the simulation are analyzed.

Intelligent Information

This paper presented a new method based on the Fuzzy self - adaptive PID for BLDCM. This method overcomes some defects of the traditional PID control. Such as lower control precision and worse anti - jamming performance. It dynamic model of BLDCM was built, and then design method for TS fuzzy PID model is given, At last, it compared simulation results of PID control method with TS Fuzzy PID control method. The results show that the TS Fuzzy PID control method has more excellent dynamic antistatic performances, as well as anti-jamming performance. The experiment shows that TS fuzzy PID control has the stronger adaptability robustness and transplant.

The test rig for hydro-pneumatic converter used in straddle type monorail vehicles was researched, and its electro-pneumatic proportional control system was set up and simulated based on AMESim/Simulink. Compared fuzzy-PID (Proportion Integral Derivative) controller with PID controller through fuzzy logic tool box in Simulink, the results indicate that, this electro-pneumatic proportional control system can meet design requirements better, and fuzzy-PID controller has higher accuracy and stability than PID controller.
