Abstract :
The temperature control system of heat exchanger in district heating is a nonlinear system with strong heat inertia and large time lag. Classical PID control dissatisfies static characteristics and dynamic characteristics of the system during its control process. According to this case, an adaptive fuzzy sliding mode controller is designed based on stability theory of Lyapunov for the system. Simulation results show that the system with adaptive fuzzy sliding mode controller has better rapidity, strong robustness and high control precision, as compared with the system of PID control. The controller is very suitable for the temperature control system of heat exchanger. It is also suitable for other temperature control system of industrial processes. Therefore it has a high value of application.
