In the most industrial processes, products are weighed in motion using dynamic weighing systems before the measurement has taken place. There are many kinds of influence factors that affect weighing process. The accuracy of measurement and speed of dynamic response is closely related to the performance of the dynamic weighing system, which are contradictory each other. It is necessary to address these impacts on dynamic weighing system. To compensate affection caused by these factors, an improved adaptive dynamic state estimation (ADSE) algorithm running on the controller of dynamic weighing system for a gravimetric filling machine is proposed in this paper. The ADSE algorithm regards the weighing process as a finite state that controls state migration by estimating the next state of measurement and dynamic compensation for in-flight material. Compared with static compensation algorithm and dynamic compensation algorithm, the results showed that ADSE algorithm can provide accurate measurement and excellent dynamic response.
