Dynamic weighing under nonzero initial conditions
W.-Q. Shu · IEEE Transactions on Instrumentation and Measurement · 1993
The discrete output error (OE) model of second order is derived for the weighing system dynamics. Using the model and the recursive least squares (RLS) procedure, model parameters and then the mass being weighed can be estimated from a dynamic measurement signal of very short duration. The validity and the accuracy of this method are illustrated by digital simulation studies and real-life measurements.>
