Simulation Research on Fuzzy Self-adaptive PID Control System of Biomass Boiler

According to the structure model of fuzzy self-adaptive PID controller,the simulation model of the fuzzy self-adaptive PID system is built on MATLAB/SIMULINK,the implementation method of the simulation of the fuzzy self-adaptive PID is presented and the application research on the subsystem of biomass boiler is given.The comparison of the reaction on the interference signal between the normal PID control algorithm and the fuzzy self-adaptive PID control algorithm shows that,the system based on fuzzy self-adaptive PID has not only strong anti interference performance,flexibility and strong adaptability,but also the predominance of the higher control precision.
