Abstract
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 is proposed, which combines the advantages of PID control and fuzzy control to realize non-disturbance switching of control variables. Simulation results show that compared with single-loop PID control, this scheme has obvious advantages in terms of speed, accuracy, and anti-interference ability.
