摘要
针对具有大滞后、时变性和控制动作单向性等特点的炉温控制系统,提出了一种比例、积分自校正PID算法与多修正因子模糊控制算法相结合的Fuzzy-PID复合控制算法;以西门子PLC为控制核心,以固态继电器为执行器,通过调功的方法来达到控制温度的目的;并在具体实验中对比了多种控制算法的控制效果,验证了该设计方法的优越性和有效性。
In this paper a fuzzy-PID control algorithm is proposed for the temperature control of a large-lag, time-varying furnace. The control system is based on a programmable logic controller (PLC) and using solid state relay (SSR) as actuator to control the temperature .The experimental curves under different algorithms are also given.
