A heating system control strategy combining Smith predictor compensation and integral separation PID is proposed to address the issues of high time delay,low precision of traditional PID strate-gy control,and easy generation of overshoot and static errors in heating control systems.Firstly,a Smith predictor compensator was designed for the water supply temperature control system to reduce the impact of thermal inertness on control performance.Secondly,an integral separation strategy was proposed to e-liminate static errors.Finally,deploy and debug the Smith predictor compensator and integral separated PID in the PLC control system,and conduct practical research.Practice has proven that the control strat-egy combining Smith's predictor compensation and integral separation PID can minimize the impact of large time delays on the heating system,effectively improving the control accuracy and performance of the system.
