| Abstract: | For the temperature control system of the infant incubator, the problems with nonlinearity, slow time-varying and large inertia are difficult to tackle when a traditional PID control algorithm is adopted, which makes the precision temperature control hard to achieve. In this paper, a fuzzy neural PID control algorithm is designed. The fuzzy algorithm is used to adjust the proportion coefficient, the proportion learning efficiency, the integral learning efficiency and the differential learning efficiency of the neural PID control algorithm. The model of the temperature control system of infant incubator is constructed on the basis of the mechanism analysis and the step response method, and is simulated with MATLAB. The experimental results suggest that the proposed system features higher precision, better stability and faster response. |
