基于模糊PID控制的电锅炉控制系统的设计

Design of Control System for Electric Boiler Based on Fuzzy PID Algorithm

将模糊控制引入到常规PID控制中,设计了一种基于模糊PID控制的电锅炉温度控制系统。与常规PID控制器和模糊控制器相比,模糊PID控制改善了温度控制系统的动态性能,并能更快地达到最优温度。采用MATLAB中的Simulink和Fuzzy工具箱,对电锅炉模糊PID控制系统进行了仿真分析。结果表明参数自整定模糊PID控制效果达到了电锅炉温度控制系统的性能指标。以AT89C51单片机为控制核心,设计了温度智能控制器,实现了温度的采集与控制、超限报警等各种功能。

Combining fuzzy algorithm with conventional PID control,a fuzzy PID parameter self-tuning temperature controller of electric boiler was designed in this paper.Compared with conventional PID and fuzzy control,the fuzzy PID control can improve the dynamical performance of temperature controller and reach optimum temperature rapidly.The fuzzy PID control system was simulated and analyzed by using simulink and fuzzy logic tools in MATLAB.The simulation results illustrate the parameter self-tuning fuzzy PID control can satisfy performance requirements of the electric boiler temperature control system.In order to acquire and control the temperature,and giving alarm,a temperature controller for the electric boiler was designed based on AT89C51 in this paper.
