Research on Temperature Control System Based on Intelligent Electronic Boiler

The electric boiler in use at present has a significant system inertia and a serious time-lag at the same time the difficulty of building the mathematical model. In this paper, a study based on the electric boiler is presented to meet the demands of stable system, shorter regulating time and a small overshoot. When fuzzy control is used, regulating time and overshoot always can achieves the specification, but system cause steady-state error. So it comes to a new method of combining them together. The parameters of Kp, Ki and Kd are adjust by fuzzy inference. Experimental results illustrate that the fuzzy PID parameters controller achieved the system performance index. The method of fuzzy PID control is a ideal method.
