Control strategy for weight-lost weigher blending process with fuzzy control

Abstract：Fuzzy control principle, method of input, output-fuzzy, fuzzy decision-making rules and reason, and method of converting fuzzy value to accuracy value are introduced.Material weight error and the variation were served as inputs, feeder speed of electromagnetic vibrating feeder is served as output for the control process.By adopting fuzzy decision-making and according to changes of blending state to adjust blending speed on time, the blending accuracy and blending speed is improved to obtain better ecomocical benefits.
