摘要
After heat is metered in each house unit,the heating system is regulated by variable flow.The temperature of the return w ater is controlled to regulate the flow to realize the temperature regulation.According to the characteristics of the temperature control w ith big inertia,pure time-delay and degeneration,a fuzzy adaptive PID controller is designed w ith the advantages of the fuzzy control and PID algorithm,and the simulation model is established according to the characteristics of heating metering system.Simulation results show that the fuzzy adaptive PID controller proposed has small overshoot,short oscillation cycle,high precision and strong anti-jamming capability in comparison w ith conventional PID controller,w hich could meet the requirement of the dynamic and steady-state performance of the heating process.
After heat is metered in each house unit, the heating system is regulated by varia- ble flow. The temperature of the return water is controlled to regulate the flow to realize the temperature regulation. According to the characteristics of the temperature control with big inertia,pure time-delay and degeneration, a fuzzy adaptive PID controller is designed with the advantages of the fuzzy control and PID algorithm, and the simulation model is established according to the characteristics of heating metering system. Simulation results show that the fuzzy adaptive PID controller proposed has small overshoot, short oscillation cycle, high precision and strong anti-jamming capability in comparison with conventional PID controller, which could meet the requirement of the dynamic and steady-state performance of the heating process.
