Adaptive filtering approach to dynamic weighing: a checkweigher case study

Abstract

Dynamic weighing, i.e., weighing of objects in motion, with out stopping them on the weighing platform, allows one to increase the rate of operation of automatic weighing systems used in industrial production processes without compromising their accuracy. The paper extends and compares two approaches to dynamic weighing, based on system identification and variable-bandwidth filtering, respectively. Experiments, carried on a conveyor belt type checkweigher, show that when appropriately tuned, both approaches yields satisfactory results that meet stringent metrological accuracy specifications.
