模糊PID控制在曲料混合系统中的应用

Application of Fuzzy PID Controller in Starter Materials Mixing System

针对目前所压制的曲块含水率不稳定,以模糊控制原理为基础,通过模糊推理和PID控制相结合,设计了Fuzzy-PID控制器,应用Matlab/Simulink进行了仿真。结果表明,模糊PID控制器与PID控制器相比,表现出良好的动态响应特性、抗干扰性、稳态性,实现了曲块的含水率在线自适应调节。(孙悟)

In view of unstable moisture content in caky starter, Fuzzy-PID controller was designed based on fuzzy control principles by the combination of fuzzy reasoning and PID control. Furthermore, the simulation test was operated by Matlab/Simulink. The results showed that fuzzy PID controller had better performance in dynamic response, anti-interference and stability compared with PID controller and its use could realize on-line adaptive regulation of moisture content in caky starter.
