Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is made a detailed explanation.
A kind of loose leaves moisting moisture content control device as shown in Figure 1, this device comprise Fuzzy Control clamp dog 1 and the PID controll block 2 of the stack that is in parallel.As shown in Figure 2, Fuzzy Control clamp dog 2 comprises defuzzification interface 3, rule base 4, database 5, inference machine 6 and ambiguity solution interface 7.As shown in Figure 3, the whole model PID control end of PID controll block 2 adopts Digital PID Controller, and its closed-loop feed-back type can improve control accuracy; Fuzzy controller carries out obfuscation with the PID output quantity first, then quoting the database 4 of foundation and the rule base 5 of definition performs calculations in inference machine 6 in order to can make timely adjustment, by ambiguity solution interface 7 it is carried out the data layout reduction at last, on the output interface that finally superposes.Whole control model adopts the mode of PID and fuzzy control stack in parallel, can satisfy like this requirement of exact matching control, and the pre-judgment mechanism of supplied materials moisture can realize that in time the oneself adjusts simultaneously, reaches the purpose that improves the moisture control ability.
In PID controll block 2, the moisture value r (t) that the moisture detector in existing loose leaves moisting cylinder exit gathers, according to this moisture deviation value e (t) that is worth going out, wherein c (t) is loose leaves moisting cylinder moisture content of outlet setting value.
e(t)=r(t)+c(t)
Digital PID Controller is done respectively ratio P, integration I, differential D computing to e (t) again, and the result who obtains consists of controlled quentity controlled variable u (t) by linear combination, thereby the aperture of controlling the priming valve door reaches the purpose of stabilization of export moisture.
