Abstract :
For the thermoelectric heat pump drying temperature control problems of nonlinear, considerable inertia and long time delay, etc., design a kind of sectional type temperature control system which is based on fuzzy control. To validate temperature system control performance, the improvement based on the analysis of traditional fuzzy control technology, conducted fuzzy piecewise type control experiment for resistance furnace based on conventional fuzzy control and interpolation algorithm. The results indicate that, comparison with conventional fuzzy control, based on the location of the interpolation algorithm of control algorithm can realize multi-channel and sectional type temperature control, which can effectively restrain the pure time delay of control system of the influence, and which has the advantages of small overshoot, high precision and good stability, etc.
