Temperature Control System Based on Fuzzy Self-Adaptive PID Controller

The temperature control system has the characteristic of non-linearity, large inertia and time variability. It is difficulty to overcome the effects of these factors and get the satisfactory results with using the normal PID controller. Therefore, a self-adaptive PID controller based on fuzzy is adopted in this paper. By the means of adjusting the adjustable factors on line, it can optimize the control process continuously, so that the fuzzy control system has a strong self-adaptive capacity. The simulation results show that the fuzzy self-adaptive PID controller has good robustness, rapidity and good dynamic performance.
