Adaptive Fuzzy Pid Control

To solve the self-control problem of grouting pressure stabilization in grouting engineering, a grouting pressure stabilization control system based on adaptive Fuzzy-PID control was studied. Grouting pressure was dynamically measured and controlled by this system with sensor technology, microcomputer technology and control technology, the interface between the sensor and the host computer was designed. Based on 80C196 chip microcomputer，KP，KI and KD of PID control are automatically adjusted by fuzzy control rule，and electric control valve was controlled to keep grouting pressure precise and stable by adaptive Fuzzy-PID Control. Simulation experiments results show that: the system is able to adapt to changes of object parameter, and achieves the desired targets with good control quality, high accuracy and fine stability.

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.

In view of the fact that the performance of any conventional PID control can t meet the requirement an electric boiler temperature control system, this paper puts forward a kind of improved algorithm for tuning the PID parameters. an adaptive fuzzy controller with adjusting factor is proposed in this paper. Experimental results illustrate that the adaptive fuzzy PID controller achieved the system performance index. The method of adaptive fuzzy PID control is a ideal method.
