Abstract
This paper concerns an application-oriented study of improving the measuring speed and accuracy of an industrial weighing system from the viewpoint of modern control theory. The problem of improving the dynamic performance of the system has been formulated as a stochastic control problem, i.e., a linear regulator problem with inaccessible state variables and a noisy observation. A new concept of computer-aided dynamic measurement method has been proposed. Feasibility studies have been carried out by both computer simulation studies and on-line computer-control experiments. Results of feasibility studies give us several new and promising aspects of the present measuring method.
