    摘要: A powder measuring device and powder measuring mixer in which powder is supplied from a supply hopper to a measuring hopper with its flow rate controlled by a flow regulator associated with the hopper. The weight of the measuring hopper is monitored. A controller compares the measured weight with a target rate to produce a deviation therebetween and a time variation of the deviation. The controller operates according to fuzzy inference to produce a desired flow rate for the next control cycle. This desired flow rate is then supplied to the flow regulator. Several supply hoppers with associated flow regulators can be used. Then the output of the controller is switched between the different flow regulators at different phases of the mixing measurement. Additionally, the measuring hopper can be movable between the different supply hoppers so as to avoid complicated piping.
