模糊PID控制器在糖厂清汁加热中的应用研究

摘要

According to the control requirements of clear juice heating process, we use fuzzy-PID controller for temperature control. Based on rigorous mechanism, we build a steady state model of clear juice heater, achieved such model and the fuzzy-PID controller in MATLAB environment. The controller is used for the heater exit temperature control. Simulation result indicates that the controller has a superior anti-jamming ability and adaptability, and it can meet the high standards of system requirements.%根据糖厂清汁加热过程的控制要求，提出将模糊PID控制算法用于清汁加热过程的温度控制。我们搭建了基于严格机理的清汁加热器模型，在MATLAB环境下实现模糊PID控制器和清汁加热器模型，将模糊PID控制器用于清汁加热器温度控制。仿真结果表明模糊PID控制器具有抗干扰能力、对系统变化的适应能力，控制精度优越，能够满足高标准的系统要求。
