Research and Simulation of Dual-Mode Temperature Control System in Heat Exchange Station

针对换热站温度控制问题,基于二维切换条件与积分初值跟踪算法,提出一种PID-FUZZY双模控制策略,结合PID控制与模糊控制优点的同时实现控制量无扰切换。仿真结果表明,相比于单回路PID控制,该方案在快速性、准确性、抗干扰能力等方面均具有明显优势。

Aiming at the problem of temperature control in heat exchange stations,based on two-dimensional switching conditions and integral initial value tracking algorithm,a PID-FUZZY dual-mode control strategy was proposed,which combines the advantages of PID control and fuzzy control to realize non-disturbance switching of control variables.Simulation results showed that compared with single-loop PID control,this scheme has obvious advantages in terms of speed,accuracy,and anti-interference ability.
